Field
23.0.5.53 Port H Interrupt Flag Register (PIFH)
Read: Anytime.
Write: Anytime.
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 PPSH register. To clear this flag, write logic level “1” to the
corresponding bit in the PIFH register. Writing a “0” has no effect.

Interrupt Enable Port H
0 Interrupt is disabled (interrupt flag masked).
1 Interrupt is enabled.
Interrupt Flags Port H
0 No active edge pending. 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).
7
0
Writing a logic level “1” clears the associated flag.
