Hi 78621251@qq.com,

This is a software reset.

Which registers can be cleared manually for non power-on reset so that they are the same as power-on reset status

There is no list of registers that are cleared on POR only.

Each registers has its own specification.

For example:

Hi 78621251@qq.com,

Some registers are reset only on power-on reset.

Could you read the RCM_SRS during startup to find the source of the reset?

Thanks,

BR, Daniel

Hi 78621251@qq.com,

If you see RCR_PIN = 1, that means that another device connected to the reset_b pin is the cause of the reset, not the MCU itself.
