Nineteen (19) registers control LCD driver module operation:
The LCD control register (LCDCR):
LCDE — LCD Enable
FC — Fast Charge
LC — Low Current

This read/write bit enables the LCD driver module; the backplane and
frontplane drive LCD waveforms out of BPx and FPx pins. Reset
clears the LCDE bit.
These read/write bits are used to select the value of the resistors in
resistor ladder for LCD voltages. Reset clears the FC and LC bits.
1 = LCD driver module enabled
0 = LCD driver module disabled
