22.3.2.51 Port H Polarity Select Register (PPSH)
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.
22.3.2.52 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.

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.
