This column does not contain an exhaustive list of functions on that pin. Rather, it includes peripheral communication
functions (such as CAN and LINFlex Rx) that could be used to wake up the microcontroller. DSPI pins are not included
because DSPI would typically be used in master mode.

WISR, IRER, WRER, WIFEER, WIFEEF, WIFER, WIPUER
3
Port not required to use timer functions.

Unavailable WKPU pins must use internal pullup enabled using WIPUER.
