5.7.3 LCD controller/driver control registers
The LCD controller/driver is controlled by the following three registers.
LCD display mode register 0 (LCDM0)
LCD clock control register 0 (LCDC0)
Port function register 8 (PF8)
(1) LCD display mode register 0 (LCDM0)
This register is used to enable/disable operation, and set the operation mode and the supply of power for LCD drive.
LCDM0 is set using a 1-bit or 8-bit memory manipulation instruction.
RESET input sets this register to 00H.

Note To reduce power consumption when the LCD display is not being used, set VAON0 and LIPS0 to 0.
Cautions 1. Always set bits 0 to 3 and 5 to 0.
2. When manipulating VAON0, observe following procedure.
A. When internal booster is stopped after changing to the display off condition from the
display on condition
1) Set the display off condition by setting LCDON0 = 0.
2) Set all segment buffers and common buffers to output disabled by setting LIPS0 = 0.
3) Stop the booster by setting VAON0 = 0.
B. When the booster is stopped in the display on condition
This is prohibited.
Be sure to stop the booster after changing to the display off
condition.
C. When the display is turned on from the booster-stoped condition
1) Wait about 500 ms after starting the booster by setting VAON0 = 1.
2) Set all segment buffers and common buffers to signal output unselected by setting
LIPS0 = 1.
3) Set the display on condition by setting LCDON0 = 1.
