The Liquid Crystal Display (LCD) driver module
generates the timing control to drive a static or
multiplexed LCD panel. It also provides control of the
LCD pixel data. The module can drive panels of up to
192 pixels (48 segments by 4 commons) in 80-pin
devices, and 132 pixels (33 segments by 4 commons) in
64-pin devices.
