Reset state
Display OFF : No LCD driving mode (Output: VSS Level)
Turn off OSC circuit and LCD power supply circuit. (Synchronized with frame freq)
Display ON : LCD driving mode
Turn on OSC circuit and LCD power supply circuit.
Read data from DDRAM and display to LCD.
LED port and GPO port output states are not affected by a Display on/off state
Output state is determined by command setup (OUTSET GPOSET, PWMSET) and INHb terminal state,
respectively. For more details, please refer to each command description.
