When the LCD driver module is disabled (LCDE = 0), the LCD display
will be OFF, all backplane and frontplane drivers have the same
potential as V
power consumption.
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
