Hi ，

I have already implemented the MCU to enter shutdown and the MCU to wake up from shutdown.

I don't know where the software ran after the MCU woke up?

Where is the software entrance after MCU wakes up?

Thanks，

Libo

Hi Libo,

Here is a description in Page 53 of TRM. In shutdown, the core regulator is completely disabled and all SRAM and register contents are lost.

So the code will run from beginning.
