The XC87x has 40 port pins organized into five parallel ports: Port 0 (P0), Port 1 (P1),
Port 3 (P3), Port 4 (P4) and Port 5 (P5). Each pin has a pair of internal pull-up and pull-
down devices that can be individually enabled or disabled. These ports are bidirectional
and can be used as general purpose input/output (GPIO) or to perform alternate
input/output functions for the on-chip peripherals. When configured as an output, the
open drain mode can be selected.
