22.3.2.43 Port P Polarity Select Register (PPSP)
Read: Anytime.
Write: Anytime.
This register serves a dual purpose by selecting the polarity of the active interrupt edge as well as selecting
a pull-up or pull-down device if enabled.
22.3.2.44 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.
