This section shows the timing examples of the LCD output waveforms for the several modes of operation.
As shown in
24.4.1.4.1
Duty=1/2:DUTY[2:0] = 001
LCD pin 0 (LCD[0])and LCD pin 1, LCD[1] enabled as backplanes:
BPEN0 =1 and BPEN1 =1 in the LCDBPEN0
LCD[0] assigned to Phase A: LCDWF0 = 0x01
LCD[1] assigned to Phase B: LCDWF1 = 0x02
