Description
This command causes the LCD module to enter the minimum power consumption mode.
In this mode e.g. the DC/DC converter, Internal oscillator, and panel scanning are all stopped.
MCU interface and memory are still working and the memory keeps its contents.
This command has no effect when module is already in sleep in mode. Sleep In Mode can only be left
by the Sleep Out Command (11h).
Restriction
It will be necessary to wait 5msec before sending next command, this is to allow time for the supply
voltages and clock circuits to stabilize.
It will be necessary to wait 120msec after sending Sleep Out command (when in Sleep In Mode)
before Sleep In command can be sent.
