7.2.20 Power Save (Compound Command)

The power save mode is entered when the display all points ON command is executed

while in the display OFF mode. The power save mode includes the sleep mode and the

standby mode. The sleep mode is entered when the static indicator is OFF, and the

standby mode is entered when the static indicator is ON. This mode is cleared by the

display all points OFF command.

The sleep mode operation stops all operations in the LCD display system, and as long

as there are no accesses from the MPU. In sleep mode operation, the oscillator circuit,

the LCD power supply circuit, and all LCD driver circuits are put on halt.

Release the Sleep mode using both Power Save OFF command (Display ON

command or Entire Display OFF command) and Set Indicator On command.
