Supply
The table above shows the states of the power supply, display data, and timing signals for the
typical LCD module in its active and stopped states. Some of the supply voltages described may
not be necessary, because some modules internally generate the power supply required for high-
voltage systems from the logic-level power-supply voltage.
Notes on display-off mode (LCDC stopped):
If LCD module power-supply control-sequence processing is in use by the LCDC or the supply of
power is cut off while the LCDC is in its display-on mode, normal operation is not guaranteed. In
the worst case, the connected LCD module may be damaged.
