Note: * Applies to the H8/38124 Group only. On the H8/38024, H8/38024S, and H8/38024F-ZTAT
Group, these bits are reserved like bit 4.
LCR2 is an 8-bit read/write register which controls switching between the A waveform and B
waveform and removal of split-resistance. Note that removal of split-resistance control is only
implemented on the H8/38124 Group.
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.
