Liquid Crystal Display Driver (LCD)
16.7 I/O Signals
16.7.1 BP0–BP3 (Backplane Drivers)
Technical Data
326
The LCD driver module has thirty (30) output pins and shares eight of
them with port C I/O pins.
BP0–BP3 are the backplane driver output pins. These are connected to
the backplane of the LCD panel. Depending on the LCD duty selected,
the voltage waveforms in
appear on the backplane pins.
BP3 pin is only used when 1/4 duty is selected. The pin becomes FP0
for static and 1/3 duty operations.
DUTY = 1/3
NOTES:
1. BP3 is not used.
2. At 1/3 duty, 1FRAME has three times the cycle of LCD waveform base clock.
