### Bug Fixes

* **aes**
  * (B91/B92)Solved the problem that the aes modified the e0 address pointer, causing the BT communication to be abnormal.(merge_requests/@1273)
* **pm**
  * (TL721X)Solves an issue where users cannot sleep and wake up normally when all interrupt priorities such as PM are initialized to 0 during initialization.(merge_requests/@1332)
  * (TL321x)Solved the issue of possible SRAM loss when entering suspend sleep after deep retention sleep. (merge_requests/@1480)
* **sys** 
  * (TL721X)The problem of frequency deviation caused by too short reservation of crystal starting time is solved.(merge_requests/@1332)
* **ske** 
  * (TL321X/TL721x)Addressed the issue where the software did not check the busy signal bit before writing to the SKE register, leading to data errors caused by repeated software triggering of calculations before the SKE computation was complete.（merge_requests/@1331, merge_requests/@1340）
* **audio**
  * (B91)Fixed the problem that i2s pin input function could not be used because gpio_shutdown(GPIO_ALL) was called during initialization.(merge_requests/@1351)
  * (TL721x/TL321x)Fix BUFFER_TO_LINEOUT demo waveform distortion issue.(merge_requests/@1472)
* **rf**
  * (B91/B92)Fixed an issue where incorrect configuration during the enable and disable of fast settle caused the settle process to deviate from the expected behavior, potentially leading to a degradation in RF performance.(merge_requests/@1354)
* **adc**
  * (TL721x)1.A2 test PB0 PD1 PD2 three pins capture voltage performance slightly worse than other pins, so remove. 2.Test found that enabling dwa affects adc performance so don't use this feature. 3.pre_scale = 1/4 Fixed on A2, already open.(merge_requests/@1428,merge_requests/@1445)

### BREAKING CHANGES

* **uart**
  * (TL721x/TL321x)uart_set_rx_timeout: For compatibility, change it to uart_set_rx_timeout_with_exp.(merge_requests/@1338)
* **audio**
  * (TL721X)Adjusted the parameter's position of audio_rx_dma_chain_init and audio_tx_dma_chain_init to make their function prototypes consistent with other chips.(merge_requests/@1342)
  * (B91)Fixed i2s pin definition in audio_i2s_set_pin interface. Swapped adc_dat and dac_dat, adc_lr and dac_lr.(merge_requests/@1351)
  * (TL721X)Change the name of the audio_i2s_set_mclk interface to audio_set_codec_clk_as_mclk, and the name of the audio_aclk_debug_set_mclk interface to audio_set_debug_clk_as_mclk, and add the following function to gpio_func_e function in gpio_func_e.(merge_requests/@1401)
* **spi**  
  * (TL321x)gspi_cs_pin_en: Interface formal parameter type changed from gpio_pin_e to gpio_func_pin_e.(merge_requests/@1320)
  * (TL321x)In order to keep the value of GSPI_MODULE in enumeration variable spi_sel_e consistent with other chips, GSPI_MODULE=0 is modified to GSPI_MODULE=1, involving the interface as follows:spi_hw_fsm_reset/spi_set_error_timeout/ spi_get_error_timeout_code/gspi_timeout_handler/spi_master_send_cmd/spi_write/spi_read/spi_master_write/spi_master_write_read/spi_master_write_plus/spi_master_write_repeat/spi_master_write_repeat_plus/spi_master_read_plus/spi_master_write_read_plus.(merge_requests/@1355)
* **rf**
  * (TL721X):In order to fix the issue of TX drift failure in 2M mode under high TX power, increase the preamble length of 2M mode to 7 bytes.(merge_requests/@1431)
* **sys**
  * (TL721x/TL321x)In the new version, after calling sys_init(), if you want to get the value of g_pm_status_info.mcu_status or call pm_get_reboot_event() to get related information, you won't be able to. The application layer needs to call pm_update_status_info() to obtain it. The new usage method is as follows:After calling sys_init(), call pm_update_status_info(), and you can get the value of g_pm_status_info.mcu_status. Additionally, the reboot classifications have been changed as follows:1.Two new statuses have been added to g_pm_status_info.mcu_status: MCU_HW_REBOOT_TIMER_WATCHDOG and MCU_HW_REBOOT_32K_WATCHDOG.2.The meaning of MCU_STATUS_REBOOT_BACK has changed. Previously, it included both software reboots and watchdog reboots. In the new version, MCU_STATUS_REBOOT_BACK only represents software reboots. The functions pm_get_reboot_event() and pm_get_deep_retention_flag() have been removed.(merge_requests/@1268)
* **adc**
  * (TL721x)The A2 chip changes the adc reference voltage 0p9 to 1p2 for gpio sampling, so the enumeration name is changed: ADC_VREF_0P9V->ADC_VREF_GPIO_1P2V,ADC_VREF_1P2V->ADC_VREF_VBAT_1P2V.(merge_requests/@1445)
  * (TL721x)A2 chip multi-channel sampling has the problem of inter-channel interference, so this function is not open to the public.(merge_requests/@1445)

### Performance Improvements
* **rf**
  * (TL321X)Modify the rf_set_xx_xx_mode() function configuration to improve the bandage performance of 2M phy mode.(merge_requests/@1296)
  * (TL721X)Modify the configuration of the rf_mode_init() function to improve the performance of fdev.(merge_requests/@1326)

### Note
* (B92/TL721x/TL321x) Update toolchains from V5.3.0 to V5.3.x
* (B91/B92/TL721X/TL321X) Add usb_set_pin() interface, in USB application can choose to enable or disable dp_through_swire function, for compatibility usb_set_pin_en() is defined as usb_set_pin(1) and comments were added to cstartup.S.

### BREAKING CHANGES

* **sys**
  * (TL321X)Add power_mode parameter into sys_init(A0 version only support LDO, A1 version support both LDO and DCDC_LDO) and update sys_init to adapt the chip A1 version.
  * (TL721x/TL321x)In the new version, after calling sys_init(), if you want to get the value of g_pm_status_info.mcu_status or call pm_get_reboot_event() to get related information, you won't be able to. The application layer needs to call pm_update_status_info() to obtain it. The new usage method is as follows:After calling sys_init(), call pm_update_status_info(), and you can get the value of g_pm_status_info.mcu_status and call pm_get_sw_reboot_event to check the reason for the software reboot.Additionally, the reboot classifications have been changed as follows:1.Two new statuses have been added to g_pm_status_info.mcu_status: MCU_HW_REBOOT_TIMER_WATCHDOG and MCU_HW_REBOOT_32K_WATCHDOG.2.The meaning of MCU_STATUS_REBOOT_BACK has changed. Previously, it included both software reboots and watchdog reboots. In the new version, MCU_STATUS_REBOOT_BACK only represents software reboots. If you want to know the specific reason for a software reboot, you can call pm_get_sw_reboot_event to check. The functions pm_get_reboot_event() and pm_get_deep_retention_flag() have been removed.
  * (TL721x/TL321x)Previously, the reasons for software reboots could coexist in multiple situations. To save register bits for future expansion, the new version only saves the reason for the most recent software reboot. Therefore, if you want to save all software reboot reasons, the upper application needs to save them after each initialization to prevent losing the history of reboot reasons.
  * (TL721x/TL321x)Function name changes:sys_set_power_mode -> pm_set_power_mode, sys_set_vbat_type -> pm_set_vbat_type.
* **dma**
  * (B92/TL321x/TL721x) Change the interface for setting the interrupt mode of linked list DMA from dma_set_llp_int_mode to dma_set_llp_irq_mode, and unify the enumeration type of the interrupt mode to dma_llp_irq_mode_e.
* **audio**
  * (B92) Change audio_set_i2s_align_en,audio_set_i2s_align_dis interface name to audio_i2s_align_en,audio_i2s_align_dis.
* **emi**
  * (B91/B92/TL721X/TL321X)Modify the emi. c rf_comtinue_made_run interface to add configurable packet data types and adjust the correspondence between command values and data types from (0: pbrs9 1: 0xf0 2:0x55) to (0: pbrs9 1: 0x0f 2:0x55 3: 0xaa 4:0xf0 5:0x00 6:0xff)
  * (B91/B92/TL721X/TL321X)Renaming the original supported mode of the rf_mode parameter of the functions rf_emi_tx_continue_update_data rf_emi_rx_setup rf_emi_tx_burst_loop and rf_emi_tx_burst_setup RF_MODE_BLE_2M to RF_MODE_BLE_2M_NO_PN (the new name is closer to its mode)
* **adc**
  * (TL721x/TL321x)ADC DMA mode is optimized from round-robin mode to DMA interrupt mode to read data, which improves the efficiency of code running, and at the same time rename adc_get_sample_status_dma()/adc_clr_sample_status_dma()/adc_set_dma_trig_num() to adc_get_irq_status_dma()/adc_clr _irq_status_dma()/adc_set_rx_fifo_trig_cnt(), deleted adc_get_code_dma().

### Note
* (B92/TL721x/TL321x)编译工具链从V5.3.0升级为V5.3.x。
* (B91/B92/TL721X/TL321X) 新增usb_set_pin()接口，在USB应用中可以选择使能或不使能dp_through_swire功能，为了兼容性usb_set_pin_en()定义为 usb_set_pin(1)，并在cstartup.S 添加相应注释。

### BREAKING CHANGES

* **sys**
  * (TL321X)sys_init新增power_mode参数（A0只支持LDO模式，A1支持LDO和DCDC_LDO）同时更新sys_init内容以适配A1芯片。
  * (TL721x/TL321x)新的版本调用sys_init()之后，如果想要获取g_pm_status_info.mcu_status的值，或者调用pm_get_reboot_event（）获取相关信息，获取不到了。需要应用层自己调用pm_update_status_info()获取。新的使用方法如下：调用sys_init()后再调用pm_update_status_info()，即可获得g_pm_status_info.mcu_status的值并且可以调用pm_get_sw_reboot_event查看软件重启原因。同时，之前的reboot分类也做了如下变更：1.g_pm_status_info.mcu_status新增两个状态：MCU_HW_REBOOT_TIMER_WATCHDOG 、MCU_HW_REBOOT_32K_WATCHDOG2.MCU_STATUS_REBOOT_BACK的含义和以前不一样了，以前是包含软件重启和watchdog重启。现在的版本MCU_STATUS_REBOOT_BACK仅仅代表软件重启，如果想要知道软件重启的具体原因，可以调用pm_get_sw_reboot_event进行查看。删除了pm_get_reboot_event()/pm_get_deep_retention_flag()函数。
  * (TL721x/TL321x)之前的软件reboot原因，可以多种情况共存，为了节省寄存器bit以便将来扩展使用，现在的版本只会保存最新一次软件reboot的原因。所以如果想要保存所有软件reboot的原因的话，上层应用需要每次初始化后自行保存，以防看不到历史的reboot原因。
  * (TL721x/TL321x)函数名字变更：sys_set_power_mode->pm_set_power_mode，sys_set_vbat_type->pm_set_vbat_type。
* **dma**
  * (B92/TL321x/TL721x)设置链表DMA的中断模式的接口由dma_set_llp_int_mode改成dma_set_llp_irq_mode, 将中断模式的枚举类型统一为dma_llp_irq_mode_e。
* **dma**
  * (B92/TL721x/TL321x) 将dma_set_spi_burst_size接口名称修改为dma_set_burst_size。
* **audio**
  * (B92) 将audio_set_i2s_align_en,audio_set_i2s_align_dis接口名称修改为audio_i2s_align_en,audio_i2s_align_dis。
* **emi**
  * (B91/B92/TL721X/TL321X)修改emi.c rf_continue_mode_run 接口，增加了可配置发包数据类型，调整命令值与数据类型的对应关系，由（0:pbrs9 1:0xf0 2:0x55）调整为（0:pbrs9 1:0x0f 2:0x55 3:0xaa 4:0xf0 5:0x00 6:0xff）
  * (B91/B92/TL721X/TL321X)将 rf_emi_tx_continue_update_data,rf_emi_rx_setup,rf_emi_tx_burst_loop,rf_emi_tx_burst_setup函数的rf_mode参数的原支持模式RF_MODE_BLE_2M更名为RF_MODE_BLE_2M_NO_PN（新名字更贴近其模式）
* **adc**
  * (TL721x/TL321x)ADC DMA模式从轮巡方式优化成DMA中断方式读取数据，提高代码运行效率，同时将adc_get_sample_status_dma()/adc_clr_sample_status_dma()/adc_set_dma_trig_num()改名为adc_get_irq_status_dma()/adc_clr_irq_status_dma()/adc_set_rx_fifo_trig_cnt(),删除了adc_get_code_dma()。

### Bug Fixes

* **pm**
  * (TL721x)Solved the problem of exiting the sleep function or causing a reset due to the incorrect position of the clear wake source state operation.Clear the wake source status after setting the wake tick.The process of setting the wake up tick value may generate an intermediate value. If the intermediate value is the same as the 32k tick value, the state of the timer wake up source will be set, causing the exit of the sleep function or a reset.[2b4ddd52](http://192.168.48.36/src/driver/tl_platform_src/merge_requests/1147/commits?commit_id=2b4ddd52a79331bd344548bd5bed1d5f1847f6f8)
  * (B91/B92)Solved the problem that pm_set_wakeup_time_param and pm_set_xtal_stable_timer_param interfaces calculate the early wake time of sleep incorrectly. If you call either of these interfaces, you may not be able to sleep properly.[2f9b7be4](http://192.168.48.36/src/driver/tl_platform_src/merge_requests/1159/commits?commit_id=2f9b7be4ff8e2c0018180a9df7d85d6b4c1f0db3)
* **i2c1_m**
  * (TLSR922x/TLSR952x/TL721X/TL321X)I2C1_M_WAIT:xxx_timeout_handler error passing parameter.[5fbb0b](http://192.168.48.36/src/driver/tl_platform_src/merge_requests/1162/commits?commit_id=5fbb0bc295c5a7e9e1b976a48dea8dc72333ac61)
* **RF_Demo**
  * (TL721X/TL321X)Fixed data overflow during header variable assignment in app_pri_generic_mode.c[0d5bc4](http://192.168.48.36/src/driver/tl_platform_src/merge_requests/1160/commits?commit_id=0d5bc466a3c121324dee848c4f245b1080d592ae)
  * (TL721x/TL321x)Fixed rf_set_irq_mask parameter passing error in app_pri_generic_mode.c[0d5bc4](http://192.168.48.36/src/driver/tl_platform_src/merge_requests/1160/commits?commit_id=0d5bc466a3c121324dee848c4f245b1080d592ae)
* **rf**
  * (TL721X/TL321X)Fixed issue where switching between different RF modes using rf_set_xx_mode could be unsuccessful (in cases where the rf_reset_register_value interface was not called before switching modes)[0d5bc4](http://192.168.48.36/src/driver/tl_platform_src/merge_requests/1160/commits?commit_id=0d5bc466a3c121324dee848c4f245b1080d592ae)
  * (TL321x) Fix the rf_mode_init configuration error to avoid triggering RF DMA and state machine reset during invocation.[373c5d](http://192.168.48.36/src/driver/tl_platform_src/merge_requests/1149/commits?commit_id=373c5dd45fc45afab5b38f5ea572afadcd7428a0)

### BREAKING CHANGES

* **rf**
  * (TL321x) Close the stimer_bb module in `rf_rode_init`interface; Delete the interfaces `rf_bb_timer_sync_to_stimer_en`, `rf_bb_timer_sync_to_stimer_trig`, `rf_bb_timer_get_tick`and `rf_set_timer_source`.
* **flash**
  * (B91/B92/TL721x/TL321X)Removed flash_read_data()/flash_read_data_decrypt_check(), and changed the default single-wire of flash_read_page() interface in flash.c to default two-wire to prevent the mismatch between the maximum frequency supported by flash single-wire read and the frequency configured by the chip from leading to flash read error.

### Features

* **TL321X**
  * PKE/PM
* **pm**
  * (TL721x) Added interface pm_set_cfg_for_os_compile_opt(), added enumeration pm_optimize_sel_e, and added code related to os optimization options.

* **trap**
  * (TLSR921x/TLSR951x/TLSR922x/TLSR952x/TL721X/TL321X) Added plic_all_interrupt_save_and_disable interface to save and disable all interrupt sources of PLIC, plic_all_interrupt_restore interface to restore all PLIC interrupt sources.
* **flash**
  * (B91/B92/TL721x/TL321X)add flash_4line_en() and flash_4line_dis().

### Refactoring

* **USB_Demo**
  * (TLSR921x/TLSR951x/TLSR922x/TLSR952x/TL721X/TL321X)The usb_cdc_tx_data_to_host function supports sending data of arbitrary length in a blocking fashion. usb_cdc_tx_data_to_host_non_block is added as a new non-blocking function, and sample code is provided.
* **rf**
  * (TL721x) Switch stimer_bb to manual mode in `rf_rode_init`, which triggers tick earlier.
* **aes**
  * (TL721x/TL321X)The AES section was deleted because it was not needed.

### Bug Fixes

* **pm**
  * (TL721X)解决了因为清唤醒源状态操作的位置不对引发的退出睡眠函数或者产生复位的问题。清唤醒源状态的操作需要放在设置唤醒tick之后。设置唤醒tick值的过程可能会产生中间值，如果中间值和32k tick值相同会把timer唤醒源的状态置起来，从而引发退出睡眠函数或者产生复位。[2b4ddd52](http://192.168.48.36/src/driver/tl_platform_src/merge_requests/1147/commits?commit_id=2b4ddd52a79331bd344548bd5bed1d5f1847f6f8)
  * (B91/B92)解决了pm_set_wakeup_time_param和pm_set_xtal_stable_timer_param接口对于睡眠的提前唤醒时间计算错误的问题。如果调用过这两个接口中的任意一个，可能会导致不能正常睡眠。[2f9b7be4](http://192.168.48.36/src/driver/tl_platform_src/merge_requests/1159/commits?commit_id=2f9b7be4ff8e2c0018180a9df7d85d6b4c1f0db3)

* **RF_Demo**
  * (TL721X/TL321X)修复了app_pri_generic_mode.c中header变量赋值过程中的数据溢出问题[0d5bc4](http://192.168.48.36/src/driver/tl_platform_src/merge_requests/1160/commits?commit_id=0d5bc466a3c121324dee848c4f245b1080d592ae)
  * (TL721x/TL321x)修复了app_pri_generic_mode.c中rf_set_irq_mask传参错误[0d5bc4](http://192.168.48.36/src/driver/tl_platform_src/merge_requests/1160/commits?commit_id=0d5bc466a3c121324dee848c4f245b1080d592ae)
* **rf**
  * (TL721x/TL321x)修复了使用rf_set_xx_mode切换不同RF模式可能不成功的问题（在切换模式之前没有调用rf_reset_register_value接口的情况）[0d5bc4](http://192.168.48.36/src/driver/tl_platform_src/merge_requests/1160/commits?commit_id=0d5bc466a3c121324dee848c4f245b1080d592ae)
  * (TL321x) 修复了rf_mode_init配置错误，避免调用时触发RF DMA和状态机复位。[373c5d](http://192.168.48.36/src/driver/tl_platform_src/merge_requests/1149/commits?commit_id=373c5dd45fc45afab5b38f5ea572afadcd7428a0)

### BREAKING CHANGES

* **rf**
  * (TL321x) `rf_mode_init`接口中关闭stimer_bb模块；删除`rf_bb_timer_sync_to_stimer_en`、`rf_bb_timer_sync_to_stimer_trig`、`rf_set_timer_source`、`rf_bb_timer_get_tick`接口。
* **flash**
  * (B91/B92/TL721x/TL321X)删除了flash_read_data()/flash_read_data_decrypt_check()，同时将flash.c中的flash_read_page()接口默认单线更改为默认两线，防止flash单线读支持的最大频率和芯片配置的频率不匹配导致flash读错误。

  * (TLSR922x/TLSR952x)Fixed the problem of amic and line mono input data anomaly under 44.1k and 48k sample rate, involving interface audio_codec_swap_stream0_data. [3d3f31d9](http://192.168.48.36/src/driver/telink_b91m_platform_src/merge_requests/1034/diffs?commit_id=3d3f31d94888af0f2242fcef7e8107e729ca6776)
  * (TLSR922x/TLSR952x)Solved the problem of inconsistent volume between the left and right channels of 20bit audio data in stereo mode. [716ead90](http://192.168.48.36/src/driver/telink_b91m_platform_src/merge_requests/944/diffs?commit_id=716ead90a4e0184169b082395715481ac358a1bb)
  * (TLSR922x/TLSR952x)Solved the problem of abnormal dac output after dynamically switching the codec dac sampling rate. [d755dae7](http://192.168.48.36/src/driver/telink_b91m_platform_src/merge_requests/1086/diffs?commit_id=d755dae7d81454617c3ddc0290cf07cf4a30b17f)
* **SPI_Demo**
  * (TLSR922x/TLSR952x)Repair SPI_PROTOCOL in spi no dma mode is configured as B91M_SLAVE_PROTOCOL, and the master side sends data in wrong format, modify SPI_MODE_WR_DUMMY_WRITE to SPI_MODE_WR_WRITE_ONLY. [e171fa06](http://192.168.48.36/src/driver/telink_b91m_platform_src/merge_requests/1013/diffs?commit_id=e171fa060b221eac87bef74edadb3e296890bca2)
* **pm**
  * (TLSR922x/TLSR952x)Solved several problems that may occur when the sleep time set by the function pm_sleep_wakeup() is less than 1.62ms: 1. Entered sleep, but the sleep time did not meet expectations, and it can be awakened after about 37 hours. 2. If it happens to be after the pm_clr_all_irq_status() in the processing of pm_sleep_wakeup() and the time is up, it will cause the plic_clr_all_request() to not be cleared, triggering a software reboot. 3. If it happens to be at the moment of sleep and the time was out, it will result in not entering sleep and continuing to execute (when sleep mode is suspend/sleep retention) or software reboot (when sleep mode is deep). [bd44c301](http://192.168.48.36/src/driver/telink_b91m_platform_src/merge_requests/769/diffs?commit_id=bd44c3017fd31dbb3c0808b5c8bbcb6645f38ea2)
  * (TLSR922x/TLSR952x)Solved the problem that may be caused by treating the VBUS flag bit as a wake-up source flag bit in pm_sleep_wakeup(): If jitter occurs on the VBUS pin after the pm_clr_all_irq_status() in the processing of pm_sleep_wakeup(), it will cause the plic_clr_all_request() to not be cleared, triggering a software reboot. [bd44c301](http://192.168.48.36/src/driver/telink_b91m_platform_src/merge_requests/769/diffs?commit_id=bd44c3017fd31dbb3c0808b5c8bbcb6645f38ea2)
  * (TLSR921x/TLSR951x)Solved the crash problem caused by the failure of the crystal oscillator stability flag. The program determines whether to switch from 24M rc to 24M xtal by reading the stable flag of the hardware crystal oscillator. If the crystal used starts slowly and the flag of the crystal oscillator is ready, but the actual crystal oscillator does not start normally, the program will crash after switching to 24M XTAL. [3aa5ca13](http://192.168.48.36/src/driver/telink_b91m_platform_src/merge_requests/936/diffs?commit_id=3aa5ca1363a8805e274dccf03320f584ab75e477)
  * (TLSR921x/TLSR951x/TLSR922x/TLSR952x)Restore the default value of register system_up_32k before sleep, which solves the problem of inaccurate sleep time. If the default value is not restored, the system tick updates every 32k edge. Because the system tick is not updated in a timely manner, the XTAL may be misjudged that it is not stable. If the system tick executes 40us more than once, the reserved waiting time may be exceeded, resulting in inaccurate sleep time.

### BREAKING CHANGES 
* **sys**
  * (TLSR922x/TLSR952x)Refactor the nop related macro definition to avoid stack overflow in GCC. Simultaneously updated the names of nop related macro definitions to make them more reasonable.
  * (TLSR921x/TLSR951x/TLSR922x/TLSR952x)Add the cap argument to the sys_init function to configure whether the internal capacitor needs to be turned off. If the development board has already welded the capacitor on the outside, then the internal capacitor needs to be turned off; If the development board does not weld the capacitor on the outside, then the internal capacitor needs to be opened. If the corresponding operation is not possible, there may be two capacitors in parallel, or no capacitors. This has a great impact on the starting time and frequency of crystal vibration, which may cause reset and crash.
* **pm/clock**
  * (TLSR921x/TLSR951x/TLSR922x/TLSR952x)Replace the method of obtaining microsecond level delay before the system timer starts working with core_cclk_delay_tick() instead of nop delay.
* **pm**
  * (TLSR921x/TLSR951x)Deleted DCDC_1P4_DCDC_1P8 from the enumeration power_mode_e. When the power supply voltage exceeds 3.8V and the DCDC_1P8 configuration is used, the flash voltage may exceed the power supply range when the LDO is switched to the DCDC.
  * (TLSR921x/TLSR951x)PM_ANA_REG_WD_CLR_BUF0(0x38), PM_ANA_REG_POWER_ON_CLR_BUF0(0x39) register all bits are for driver use only.
  * (TLSR922x/TLSR952x)PM_ANA_REG_WD_CLR_BUF0(0x35), PM_ANA_REG_POWER_ON_CLR_BUF0(0x3a) register all bits are for driver use only.
* **rf**
  * (TLSR921x/TLSR951x/TLSR922x/TLSR952x)The rf_mode_init() function has added an RF Rx DCOC software calibration scheme to solve the problem of poor Rx sensitivity performance in some chips with large DC-offset.
         The execution time of this function will be longer, you can check the function comment for the specific time.
         Due to the use of software DCOC's calibration scheme, it is not necessary and not allowed to use rf_get_dcoc_cal_val and rf_set_dcoc_cal_val for processing in the fast settle function,
         Therefore, the above two interfaces were deleted, and the structure rf_dcoc_cal_t was also deleted;
* **flash**
  * (TLSR921x/TLSR951x/TLSR922x/TLSR952x)Add the return value for the flash_write_status_midxxxxxx,flash_lock_midxxxxxx and flash_unlock_midxxxxxx interface.
* **stimer**
  * (TLSR921x/TLSR951x/TLSR922x/TLSR952x)Delete interface stimer_enable/stimer_disable.
* **USB_Demo**
  * (TLSR921x/TLSR951x/TLSR922x/TLSR952x) Since the -fshort-wchar compilation option was removed, using wide characters to return usb string descriptors no longer works, so use the usbdesc_get_str()/myudb_usbdesc_get_str() function to get the usb string descriptor and remove the associated usb string descriptor constants.
* **flash**
  * (TLSR922x/TLSR952x)Add the return value for the flash_write_status_midxxxxxx,flash_lock_midxxxxxx and flash_unlock_midxxxxxx interface.
* **stimer**
  * (TLSR921x/TLSR951x/TLSR922x/TLSR952x)Delete interface stimer_enable/stimer_disable。
* **USB_Demo**
  * (TLSR921x/TLSR951x/TLSR922x/TLSR952x) Since the -fshort-wchar compilation option was removed, using wide characters to return usb string descriptors no longer works, so use the usbdesc_get_str()/myudb_usbdesc_get_str() function to get the usb string descriptor and remove the associated usb string descriptor constants.
* **rf**
  * (TLSR921x/TLSR951x) For the convenience of users, the fast settle-related interfaces have been re-encapsulated. The new code will affect compatibility. Please refer to rf_demo and app_fast_settle_test.c for usage instructions. (Interfaces rf_get_ldo_trim_val, _set_ldo_trim_val, rf_get_hpmc_cal_val, rf_set_hpmc_cal_val, rf_get_dcoc_cal_val, rf_set_dcoc_cal_val, rf_tx_fast_settle_init, and rf_rx_fast_settle_init have been removed; interfaces rf_fast_settle_config, rf_tx_fast_settle_update_cal_val, and rf_rx_fast_settle_update_cal_val have been added.)
  * (TLSR922x/TLSR952x) For the convenience of users, the fast settle-related interfaces have been re-encapsulated. The new code will affect compatibility.

(Interfaces rf_rx_fast_settle_dis, rf_get_ldo_trim_val, rf_set_ldo_trim_val, rf_get_hpmc_cal_val, rf_tx_fast_settle_init, and rf_rx_fast_settle_init have been removed; interfaces rf_fast_settle_config, rf_tx_fast_settle_update_cal_val, and rf_rx_fast_settle_update_cal_val have been added.)
* **calibration**
  * (TLSR921x/TLSR951x/TLSR922x/TLSR952x)Deleted the operation on enabling the internal capacitor in the user_read_flash_value_calib (TLSR921x/TLSR951x) /calibration_func(TLSR922x/TLSR952x) interface. The calibration interface will adjust the voltage and capacitance values, so it will be called most of the time, but for 24M crystals using an external capacitor,if the internal capacitor is opened when the calibration interface is called, the two capacitors will be in parallel, affecting the crystal vibration, so this operation is deleted.
* **error_handler**              
  * drv_set_error_timeout: Delete TIMEOUT_US and change it to global variable g_drv_api_error_timeout_us, add the above interfaces for modification to avoid dynamic modification of the lib library due to macro definition.
  * error_code_e: Change the value to drv_api_error_code_e to prevent the same name.
  * get_error_code/timeout_handler: Change it to drv_get_error_code/drv_timeout_handler to prevent the same name.
* **flash_demo**
  * (TLSR921x/TLSR951x/TLSR922x/TLSR952x):In order to realize the bin firmware protection in driver sdk, delete the flash_lock/flash_unlock swtich implementation scheme maintained by flash_demo, for the sake of code simplicity and easy maintenance, add the flash hal layer to realize the scheme with structure, add the hal_flash.c/.h file and add the bin firmware protection function in platform_init. platform_init to add the bin firmware protection function.

### Performance Improvements

* **rf**
  * (TLSR921x/TLSR951x)The rf_mode_init() function uses DCOC software calibration to minimize the DC offset of the chip.
         At the same time, turn on the RX secondary filter in BLE S2 and S8 modes to filter out DC offset and noise as much as possible, in order to improve the chip's out of band anti-interference ability (including DC offset).
         These two operations can restore the sensitivity performance of chips with larger DC offset to the normal range.
         But it should be noted that opening the secondary filter will reduce the frequency offset resistance range of the chip to within ± 150kHz.

* (TLSR922x/TLSR952x)The rf_mode_init() function uses dcoc software calibration to achieve the minimum DC offset for the chip. 
         At the same time, turn on the RX secondary filter in RF modes other than private 250k and 500k to filter out DC offset and noise as much as possible, in order to improve the chip's out of band anti-interference ability (including DC offset). 
         By performing these two operations, the sensitivity performance of chips with larger DC offset can be restored to the normal range, but it is important to note that opening the secondary filter will reduce the frequency offset resistance range of the chip to within ± 150kHz.

* **pm**
  * (TLSR922x/TLSR952x)解决了当函数pm_sleep_wakeup()设置的睡眠时间小于1.62ms时，可能会引起的以下几种问题： 1.进入了睡眠，但睡眠时间不符合预期，约37小时后可以唤醒。 2.如果正好在pm_sleep_wakeup()函数中的pm_clr_all_irq_status()之后，时间到了，会导致plic_clr_all_request()清除不掉，触发软件reboot。 3.如果正好在睡眠的瞬间，时间到了，会导致不进入睡眠，继续执行（当sleep_mode是suspend/deep retention）或者软件reboot（当sleep_mode是deep）。 [bd44c301](http://192.168.48.36/src/driver/telink_b91m_platform_src/merge_requests/769/diffs?commit_id=bd44c3017fd31dbb3c0808b5c8bbcb6645f38ea2)
  * (TLSR922x/TLSR952x)解决了由于在pm_sleep_wakeup()中把VBUS标志位当成唤醒源标志位一样处理可能会引起的问题：即如果在pm_sleep_wakeup()函数中的pm_clr_all_irq_status()之后，VBUS引脚上产生抖动，会导致plic_clr_all_request()清除不掉，触发软件reboot。 [bd44c301](http://192.168.48.36/src/driver/telink_b91m_platform_src/merge_requests/769/diffs?commit_id=bd44c3017fd31dbb3c0808b5c8bbcb6645f38ea2)
  * (TLSR921x/TLSR951x)解决了因为晶振稳定标志位失效导致的死机问题。程序通过读硬件晶振稳定标志位判断是否从24M rc切换到24M xtal，如果使用的晶体起振较慢，晶振标志位ready但是实际晶振没有正常起震，切换到24M XTAL后，程序就会发生死机问题。 [3aa5ca13](http://192.168.48.36/src/driver/telink_b91m_platform_src/merge_requests/936/diffs?commit_id=3aa5ca1363a8805e274dccf03320f584ab75e477)
  * (TLSR921x/TLSR951x/TLSR922x/TLSR952x)进睡眠前恢复寄存器system_up_32k默认值，解决了睡眠时间不准的问题。如果不恢复默认值，system tick会在每个32k沿更新，由于system tick更新不及时，可能会误判XTAL还没有稳定，多判断一次，多执行40us，可能会超过预留的等待时间，而导致睡眠时间不准确。 [e8dc8082](http://192.168.48.36/src/driver/telink_b91m_platform_src/merge_requests/1078/diffs?commit_id=e8dc80828f0d9050833b55be48764dcce8733a0a)

### BREAKING CHANGES 
* **sys**
  * (TLSR922x/TLSR952x)重构了nop相关的宏定义避免GCC出现堆栈溢出。同时更新了nop相关宏定义的名字，使其更为合理。
  * (TLSR921x/TLSR951x/TLSR922x/TLSR952x)在sys_init函数中添加cap参数，用于配置是否需要关闭内部电容。如果开发板已经在外部焊接了电容，那么就需要关掉内部电容；如果开发板没有在外部焊接电容，那么就需要打开内部电容。如果不能对应操作的话，就可能会出现两个电容并联，或者没有电容的情况。这样对晶振的起振时间和晶振的频率影响很大，可能会造成复位、死机等情况发生。
* **pm/clock**
  * (TLSR921x/TLSR951x/TLSR922x/TLSR952x)将系统计时器工作前获取微秒级延迟的方法由nop延迟替换为core_cclk_delay_tick()接口.
* **pm**
  * (TLSR921x/TLSR951x)删除了枚举power_mode_e中的DCDC_1P4_DCDC_1P8。因为供电电压超过3.8V的情况下，使用DCDC_1P8配置，在LDO切换到DCDC时，flash的电压有超出供电范围的风险。
  * (TLSR921x/TLSR951x)PM_ANA_REG_WD_CLR_BUF0(0x38)，PM_ANA_REG_POWER_ON_CLR_BUF0(0x39)寄存器的所有bit仅供驱动程序使用。
  * (TLSR922x/TLSR952x)PM_ANA_REG_WD_CLR_BUF0(0x35)，PM_ANA_REG_POWER_ON_CLR_BUF0(0x3a)寄存器的所有bit仅供驱动程序使用。
* **rf**
  * (TLSR921x/TLSR951x/TLSR922x/TLSR952x)rf_mode_init()函数中新增了rf rx dcoc软件校准方案来解决部分DC-offset较大的芯片 rx sensitivity性能差的问题，该函数执行时间会变长，具体时间可以查看函数注释。因为使用了软件dcoc的校准方案，所以在fast settle功能中，不需要并且也不允许再用rf_get_dcoc_cal_val和rf_set_dcoc_cal_val进行处理，固删除了上述两个接口，同时删除了结构体rf_dcoc_cal_t;
* **flash**
  * (TLSR921x/TLSR951x/TLSR922x/TLSR952x)flash_write_status_midxxxxxxxx，flash_lock_midxxxxxx 和 flash_unlock_midxxxxxx接口增加返回值。
* **stimer**
  * (TLSR921x/TLSR951x/TLSR922x/TLSR952x)删除了接口stimer_enable/stimer_disable。
* **USB_Demo**
  * (TLSR921x/TLSR951x/TLSR922x/TLSR952x)由于 -fshort-wchar 编译选项移除，使用宽字符返回 usb 字符串描述符不再适用，所以用 usbdesc_get_str()/myudb_usbdesc_get_str() 函数获取 usb 字符串描述符并删除相关的 usb 字符串描述符常量。
* **flash**
  * (TLSR922x/TLSR952x)flash_write_status_midxxxxxxxx，flash_lock_midxxxxxx 和 flash_unlock_midxxxxxx接口增加返回值。
* **stimer**
  * (TLSR921x/TLSR951x/TLSR922x/TLSR952x)删除了接口stimer_enable/stimer_disable。
* **USB_Demo**
  * (TLSR921x/TLSR951x/TLSR922x/TLSR952x)由于 -fshort-wchar 编译选项移除，使用宽字符返回 usb 字符串描述符不再适用，所以用 usbdesc_get_str()/myudb_usbdesc_get_str() 函数获取 usb 字符串描述符并删除相关的 usb 字符串描述符常量。
* **rf**
  * (TLSR921x/TLSR951x)为了方便用户使用，重新封装了fast settle相关的接口，新的代码会影响兼容性，使用方法请注意参照rf_demo，app_fast_settle_test.c (删除rf_get_ldo_trim_val、_set_ldo_trim_val、rf_get_hpmc_cal_val、rf_set_hpmc_cal_val、rf_get_dcoc_cal_val、rf_set_dcoc_cal_val、rf_tx_fast_settle_init、rf_rx_fast_settle_init接口；新增rf_fast_settle_config、rf_tx_fast_settle_update_cal_val、rf_rx_fast_settle_update_cal_val接口)
  * (TLSR922x/TLSR952x)为了方便用户使用，重新封装了fast settle相关的接口，新的代码会影响兼容性，使用方法请注意参照rf_demo，app_fast_settle_test.c（删除rf_rx_fast_settle_dis、rf_get_ldo_trim_val、rf_set_ldo_trim_val、rf_get_hpmc_cal_val、rf_tx_fast_settle_init、rf_rx_fast_settle_init接口；新增rf_fast_settle_config、rf_tx_fast_settle_update_cal_val、rf_rx_fast_settle_update_cal_val接口)
* **calibration**  
  * (TLSR921x/TLSR951x/TLSR922x/TLSR952x)删掉了user_read_flash_value_calib（B91）/calibration_func(TLSR922x/TLSR952x)接口中对于打开内部电容的操作。校准接口会调整电压和电容值，所以大多数时候都会调用，但是对于24M晶体使用了外部电容的情况下，如果在调用校准接口时打开内部电容，会造成两个电容并联的情况，影响晶振起振，所以删掉了这个操作。
* **error_handler**              
  * drv_set_error_timeout: 将TIMEOUT_US删除,改为全局变量g_drv_api_error_timeout_us,添加以上接口进行修改,避免使用宏定义导致lib库不能动态修改;
  * error_code_e:修改为drv_api_error_code_e,为了防止重名;
  * get_error_code/timeout_handler:修改为drv_get_error_code/drv_timeout_handler,为了防止重名;
* **flash_demo**
  * (TLSR921x/TLSR951x/TLSR922x/TLSR952x):为了driver sdk实现bin固件保护,删除flash_demo维护的flash_lock/flash_unlock swtich实现方案,为代码简洁以及方便维护,改为添加flash hal层以结构体实现方案,添加hal_flash.c/.h文件,并在platform_init中添加bin固件保护功能.

### Performance Improvements

* **rf**
  * (TLSR921x/TLSR951x)rf_mode_init()函数使用dcoc 软件校准来使芯片获得最小的DC-offset,同时在BLE S2 S8模式下打开RX二级滤波器将DC-offset和噪声尽可能滤掉 ，以此来提高芯片的带外抗干扰能力（干扰包括DC-offset）。通过这两个操作可以将DC-offset较大的芯片sensitivity性能恢复到正常范围,但需要注意开二级滤波器会将芯片的抗频偏范围缩小到±150kHz以内。
  * (TLSR922x/TLSR952x)rf_mode_init()函数使用dcoc 软件校准来使芯片获得最小的DC-offset,同时在除了private 250k和500k的RF模式下打开RX二级滤波器，将DC-offset和噪声尽可能滤掉 ，以此来提高芯片的带外抗干扰能力（干扰包括DC-offset）。通过这两个操作可以将DC-offset较大的芯片sensitivity性能恢复到正常范围,但需要注意开二级滤波器会将芯片的抗频偏范围缩小到±150kHz以内。
