PTCPE[3:0]
Internal Pull Enable for Port C Bits — Each of these control bits determines if the internal pull-up device is
enabled for the associated PTC pin. For port C pins that are configured as outputs, these bits have no effect and
the internal pull devices are disabled.
0 Internal pull-up device disabled for port C bit n.
1 Internal pull-up device enabled for port C bit n.
