FAQ
What software reset should be used when switching from APROM to LDROM to execute program updates, or switching from LDROM to APROM to execute an application during the ISP (In System Programming) process? Issue Date：2016-12-20
When reset, the software reset in which the CBS [1] (Config0 [7]) is not loaded into the BS (ISPCTL [1]) is used. Thus, the user needs to use MCU Reset or CPU Reset.
- MCU Reset
Reset the entire chip, but retain the BS setting.
Function call: NVIC_SystemReset();
- CPU Reset
Reset only the CPU and Flash controller, but retain the BS setting.
Function call: SYS_ResetCPU();
