8.6.2 FP0–FP24 (Frontplane Drivers)
FP0–FP24 are the frontplane driver output pins. These are connected to the frontplane of the LCD panel.
Depending on LCD duty selected and the contents in the LCD data registers, the voltage waveforms in
Figure 8-8, Figure 8-9, Figure 8-10 and Figure 8-11 appear on the frontplane pins.
