5.4
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 com-
mon drivers.
TRISD controls the direction of pins RD0 through RD4
when PORTD is configured as a digital port.

On a Power-on Reset these pins are con-
figured as LCD segment drivers.
To configure the pins as a digital port, the
corresponding bits in the LCDSE register
must be cleared. Any bit set in the LCDSE
register overrides any bit settings in the
corresponding TRIS register.
