Hello,

Please try to go over the Bist_Run() function. After that, eventually a reset will be occurred according to the BIST sequence mentioned in RM

After reset, you can verify the status of the BIST in SCTU registers.

Best Regards,

Nam

the registers status right after the MCU is reset after executing Bist_Run().

And the attach file shows the registers list with bist run after power on reset, before Bist_SelfTestTrigger（）is call.

Please help to analyse it , Thanks.
