Freescale Semiconductor
The setting of the LCD output waveform duty is dependent on the
number of backplane drivers required. Three LCD duties are available:
When the LCD driver module is enabled the backplane waveforms for
the selected duty are driven out of the backplane pins. The backplane
waveforms are periodic and are shown are shown in

The relative potential of the LCD voltages are:

bits, LCCON[2:0].
The LCD driver module uses the CGMXCLK (see
(OSC))as the input reference clock. This clock is divided to produce the
LCD waveform base clock, LCDCLK, by configuring the LCLK[2:0] bits
in the LCD clock register. The LCDCLK clocks the backplane and the
frontplane output waveforms.
