19.2 Overview
The LCD driver generates all waveforms to drive the display. The user has only to set a 0 (segment off) or a 1
(segment on) in the bit location corresponding to the segment. The LCD driver supports the wave form generation
for different multiplexing schemes: direct drive (no multiplexing), multiplexing by 2, by 3 and by 4. The frame
frequency is software programmable. Low power on-chip voltage generation is provided for each of the different
multiplexing schemes. The LCD driver voltage is completely independent from the circuit supply voltage: the LCD
driver voltage can be below or above the circuit supply voltage. All or part of the driver can be configured as a
