Hi,

I'd like to know how to configure an pinout specific state in Halt mode.

I need a specific pin to go High in Halt mode.

Thanks, Regards

Jorge.

Jorge,

You need to handle this in software. HALT mode, by itself, does nothing to the pin states. All GPIO pins continue to remain in the same state during entry/exit of HALT mode.

Hareesh,

Thanks for your help.

My goal is to pre-define the state of the pinouts for HALT mode but, from your answer, I understand that it is not possible to do so.
(You can only change the state of the pinouts while running the program before entering HALT mode). Is this correct?
Thanks in advance.

Best regards, Jorge

Your understanding is correct. The HALT mode does not influence the state of GPIO pins. That must be handled by your code.
