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).

Writing a logic level “1” clears the associated ﬂag.
