Wake pins

Do we need to assign a wake pin? Or can we just use power up/down sequence to control the module safely?

Hi, short pressing power button can wake system.

My question was a little different than what you answered.

In the pin mux you can choose to have a pin set to wake or not - my question is do we have to have a wake pin assigned? Or is that just for optional sleep/wake functionality?

No need to do that. Just keep default setting.
