17.3.3
LCR2 controls switching between the A waveform and B waveform, selects clock for step-up
voltage circuit, selects power supply, and selects the duty ratio for charge/discharge pulse that
controls to separate power supply divider resistance from power supply circuit.

Description
A Waveform/B Waveform Switching Control
Bit 7 specifies whether the A waveform or B waveform is
used as the LCD drive waveform.
0: Drive using A waveform
1: Drive using B waveform

Triple Step-Up Voltage Circuit Clock Select
This bit selects a clock used for triple step-up voltage
circuit. This bit selects a clock which divides a clock
specified by the LCD operating control register (LCR) by
4 or 8 as step-up voltage circuit clock.
0: A clock, which divides a LCD operating clock by 4, is
1: A clock, which divides a LCD operating clock by 8, is
