LCD mode register (LCDMD)
LCDMD sets the LCD drive voltage generator.
LCDMD is set using a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation sets LCDMD to 00H.
Caution Bits 0 to 3, 6 and 7 must be set to 0.
LCD display mode register (LCDM)
LCDM is a register that enables/disables display operation, enables/disables voltage boost circuit or capacitor
split circuit operation, and sets the display data area and the display mode.
LCDM is set using a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation sets LCDM to 00H.
