SEGMENT ENABLES
The LCDSE register is used to select the pin function
for groups of pins. The selection allows each group of
pins to operate as either LCD drivers or digital only
pins. To congure the pins as a digital port, the corre-
sponding bits in the LCDSE register must be cleared.
If the pin is a digital I/O the corresponding TRIS bit con-
trols the data direction. Any bit set in the LCDSE regis-
ter overrides any bit settings in the corresponding TRIS
register.
Note 1: On a Power-on Reset these pins are con-
gured as LCD drivers.
Note 2: The LMUX1:LMUX0 takes precedence
over the LCDSE bit settings for pins RD7,
RD6 and RD5.
