Hello,
I am working on a project with the STM32G0 series microcontroller. The MCU goes into the 'SHUTDOWN' state and wakes up when the wakeup timer times out. In the reference manual, it is mentioned that wakeup with BOR (Brown-Out Reset) is not available in SHUTDOWN mode.
The manual also states that a power reset is generated when exiting from SHUTDOWN.
Additionally, it is mentioned that BOR is generated when exiting from SHUTDOWN.
Could you clarify which reset is actually occurring when exiting SHUTDOWN mode?
Solved! Go to Solution.

Hello @Anagha_Sasindran ,
Indeed the BOR is not available in shutdown mode, this is why after exiting shutdown a power-on reset is generated. For the next document revision, the mention of "brown-out reset" when exiting shutdown will be replaced by "power-on reset".
Best regards,
Simon
