F. Standby mode set
(Display all switched off and an oscillation stopped)
Standby mode realizes low power consumption of VDD, VSEG, and VCOM by all switching off a display,
stopping an oscillation of an external (COM is fixed to Low) oscillation child, and stopping internal operation
completely. All display lights OFF is primarily used for display blink and to prevent malfunction when power is
turned on.
* If a RESET signal is inputted during standby mode execution, standby mode is canceled, and keep in mind it
that all states will be initialized.

[Release standby mode]
Release in standby mode is performed in falling of CS. (An oscillation child's oscillation is started)
Data input will become possible if an oscillation is stabilized. (Please return brought-down CS high-level before
data input)
When you display after standby mode release since it is all putting out lights although the setting state is held,
please cancel all putting-out-lights modes (in usual mode).
* Please do not input a shift clock into CP until an oscillation is stabilized. (Data will be given)
tRSON (oscillation standup time) changes with oscillation children who use it. Please make reference an
oscillation child's data to be used.
