11.4.1
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 configure the pins as a digital port, the corre-
sponding bits in the LCDSE register must be cleared.

ter overrides any bit settings in the corresponding TRIS
register.
