22.6 LCD waveform examples
The following figures show the timing examples of the LCD output waveforms for the available modes of
operation. The contrast control is disabled in all examples (CCEN = 0 in LCDCCR). Selected reference
voltage is VLCD, but could also be VDDX.
22.6.1 1/1 Duty multiplexed with 1/1 Bias mode
Duty = 1/1:DUTY = 000
Bias = 1/1:BIAS = 0 or BIAS = 1
