Stop Mode Recovery Using a GPIO Port Pin Transition

Each of the GPIO Port pins may be configured as a Stop Mode Recovery input source. On

any GPIO pin enabled as a Stop Mode Recover source, a change in the input pin value

(from High to Low or from Low to High) initiates Stop Mode Recovery. In the Watch-Dog

Timer Control register, the STOP bit is set to 1.

In Stop mode, the GPIO Port Input Data registers (PxIN) are disabled. The

Port Input Data registers record the Port transition only if the signal stays

on the Port pin through the end of the STOP Mode Recovery delay. Thus,

short pulses on the Port pin can initiate STOP Mode Recovery without be-

ing written to the Port Input Data register or without initiating an interrupt

(if enabled for that pin).
