Port P interrupt flag
—
Each flag is set by an active edge on the associated input pin. This could be a rising or a falling edge based on the
state of the PPSP register. To clear this flag, write logic level 1 to the corresponding bit in the PIFP register. Writing
a 0 has no effect.
1 Active edge on the associated bit has occurred (an interrupt will occur if the associated enable bit is set).
0 No active edge pending.
