Read: Anytime. Write: Anytime.
Each flag is set by an active edge on the associated input pin. The active edge could be rising or falling
based on the state of the corresponding PPSADx bit. To clear each flag, write “1” to the corresponding
PIFADx bit. Writing a “0” has no effect.

Writing a “1” clears the associated flag.
If the ATDDIEN0(1) bit of the associated pin is set to 0 (digital input buffer
is disabled), active edges can not be detected.
