Having problems with Battery Monitoring on/off and power control

[partlydepict]

How can I monitor the state of the ON/ON button on the Teensy 4.0?
I need to display a message on the TFT when the button is pressed.

A button has two states, they can't both be ON? The T4 has a program button, that's all - are you talking about some other button in your circuit?

Bit 6 of the SNVS_HPSR register is meant to indicate the power button's current status, but I'm not sure how you expect to act on it when it turns the system off...
