PORTD is an 8-bit port with Schmitt Trigger input buff-
ers. The first five pins are configurable as general pur-
pose I/O pins or LCD segment drivers. Pins RD5, RD6
and RD7 can be digital inputs, or LCD segment, or
common drivers.
TRISD controls the direction of pins RD0 through RD4
when PORTD is configured as a digital port.
