Field
24.0.5.48 Port H Interrupt Enable Register (PIEH)
Read: Anytime.
Write: Anytime.
This register disables or enables on a per-pin basis the edge sensitive external interrupt associated
with Port H.
Field
24.0.5.49 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.

Polarity Select Port H
0 Falling edge on the associated port H pin sets the associated flag bit in the PIFH register.
1 Rising edge on the associated port H pin sets the associated flag bit in the PIFH register.

A pull-up device is connected to the associated port H pin, if enabled by the associated bit in register PERH
and if the port is used as input.
A pull-down device is connected to the associated port H pin, if enabled by the associated bit in register PERH
and if the port is used as input.
