TM4C123GH6PM: wake pin usage in the tm4c123gh6pm in my custom design

Part Number:TM4C123GH6PM

Hello,

I have a custom design, that is working for now, but I think I found an error in my design.

I have a cmos battery which I am poweing the vbat.

My wake pin is pulled up to 3v3 via 1M.

But since the 3v3 will be turned off in hibernate mode, this pin wont be really pulled up. (hibernate pin goes to voltage regulators enable pin)

So it should be pulled up to vbat?

Best regards,

C.A.
