LCR2 is an 8-bit read/write register which controls switching between the A waveform and B

waveform, and selects the duty cycle of the charge/discharge pulses which control disconnection

of the power supply split-resistance from the power supply circuit.

LCR2 is initialized to H'60 upon reset.

Bit 7: A waveform/B waveform switching control (LCDAB)

Bit 7 specifies whether the A waveform or B waveform is used as the LCD drive waveform.
