Field
24.0.5.40 Port P Interrupt Enable Register (PIEP)
Read: Anytime.
Write: Anytime.
This register disables or enables on a per-pin basis the edge sensitive external interrupt associated
with Port P.
Field
24.0.5.41 Port P Interrupt Flag Register (PIFP)
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 PPSP register. To clear this flag, write logic level “1” to the
corresponding bit in the PIFP register. Writing a “0” has no effect.
