14. Power Save mode
When setting display all-OFF using the Display OFF command and executing the Display all-lit ON command,
it changes to the Power save mode. When displaying in all-lit status and executing the Display OFF
command, it also changes to the Power save mode. In the Power save mode,
Current consumption is reduced and a value near that at standstill is attainable.
The LCD drive circuit is stopped. The Segment and Common outputs are fixed at V
DD
level.
Input is prohibited and the OSC
2
terminal floats.
Content of the display data RAM, the command and the address before the power save mode do not
change.
The Power save status is canceled through the Display ON or the Display all-lit commands.
When the LCD driver voltage is generated by division of external resistance, the electric current is passed
through this divided resistance regardless of the ICs. When reducing this current, attach a switching
transistor which cuts the current flowing to the external resistance
.
