Field Description
7-0
PIFP
Port P interrupt flag—
This flag asserts after a valid active edge was detected on the related pin (see Section 2.5.4.2, “Pin Interrupts and
Wakeup”). This can be a rising or a falling edge based on the state of the polarity select register. An interrupt will
occur if the associated interrupt enable bit is set.
Writing a logic “1” to the corresponding bit field clears the flag.
1 Active edge on the associated bit has occurred
0 No active edge occurred
