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 configure the pins as
a digital port, the corresponding bits in the LCDSE register must be cleared.
If the pin is a digital input the corresponding TRIS bit controls the data direction. Any bit set in the
LCDSE register overrides any bit settings in the corresponding TRIS register.
Example 25-1:
Example 25-2:
Note 1: On a Power-on Reset, the LCD pins are configured as LCD drivers.
Note 2: The LMUX1:LMUX0 bits take precedence over the LCDSE bit settings for pins RD7,
