Restriction
This command has no effect when module is already in sleep out mode. Sleep Out Mode can
only be exit by the Sleep In Command (10h).
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.
The display module loads all display supplier’s factory default values to the registers during this
5msec and there cannot be any abnormal visual effect on the display image if factory default
and register values are same when this load is done and when the display module is already
Sleep Out –mode.
The display module is doing self-diagnostic functions during this 5msec. See also section 7.10.
It will be necessary to wait 120msec after sending Sleep In command (when in Sleep Out mode)
before Sleep Out command can be sent.
