22.3
The LCD driver module can be configured into three
bias types:
• Static Bias (2 voltage levels: AV
• 1/2 Bias (3 voltage levels: AV
• 1/3 Bias (4 voltage levels: AV
This module uses an external resistor ladder to
generate the LCD bias voltages.
The external resistor ladder should be connected to the
Bias 1 pin, Bias 2 pin, Bias 3 pin and V
pin should also be connected to V
Figure 22-3 shows the proper way to connect the
resistor ladder to the Bias pins.
22.4
The LCD driver module can be configured into four
multiplex types:
• Static (only COM0 used)
• 1/2 multiplex (COM0 and COM1 are used)
• 1/3 multiplex (COM0, COM1 and COM2 are used)
• 1/4 multiplex (all COM0, COM1, COM2 and COM3
The LMUX1:LMUX0 setting decides the function of the
PORTE<6:4> bits (see Table 22-3 for details).

If the pin is a digital I/O, the corresponding TRIS bit
controls the data direction. If the pin is a COM drive,
then the TRIS setting of that pin is overridden.
TABLE 22-3:
22.5
The LCDSEx registers are used to select the pin
function for each segment pin. The selection allows
each pin to operate as either an LCD segment driver or
a digital only pin. To configure the pin as a segment pin,
the corresponding bits in the LCDSEx registers must
be set to ‘1’.
If the pin is a digital I/O, the corresponding TRIS bit
controls the data direction. Any bit set in the LCDSEx
registers overrides any bit settings in the corresponding
TRIS register.
