• Static Indicator Register Set
This command sets two bits of data into the static indicator register, and is used to set the static indicator into a blinking
mode.
• Static Indicator Register Set Sequence
Power Save (Compound Command)
When the display all points ON is performed while the display is in the OFF mode, the power saver mode is entered,
thus greatly reducing power consumption.
The power saver mode has two different modes: the sleep mode and the standby mode. When the static indicator is OFF,
it is the sleep mode that is entered. When the static indicator is ON, it is the standby mode that is entered.
In the sleep mode and in the standby mode, the display data is saved as is the operating mode that was in effect before
the power saver mode was initiated, and the MPU is still able to access the display data RAM.
Refer to figure 26 for power save off sequence.
