. Power Save
The power save mode is entered when the display all point ON is performed while
display OFF mode. The power save mode has 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 point OFF.
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 halted.
The standby mode operation, the duty LCD display system operations are halted and
only the static driver system for the indicator continues to operate, providing the minimum
required consumption current for the static driver. In sleep mode operation, the LCD power
supply circuit and the duty system LCD drive circuits are halted. The static drive system does
not operate and the oscillator circuit continues to operate.
