17.7.1 BP0–BP3 (Backplane Drivers)
MC68HC908LJ24/LK24 — Rev. 2.1
Freescale Semiconductor
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 = STATIC
DUTY = 1/3
NOTES:
NOTES:
1. BP1, BP2, and BP3 are not used.
2. At static duty, 1FRAME is equal to the cycle of LCD waveform base clock.
1. BP3 is not used.
2. At 1/3 duty, 1FRAME has three times the cycle of LCD waveform base clock.
