Common Output Direction (COD) set
Power Control
supply functions can be used simultaneously.
Regulator Resistor Select
power supply circuit. Refer to the table 15.
COM output scanning direction is selected by this instruction which determines the LCD driver output status.
Selects one of eight power circuit functions by using 3-bit register. An external power supply and part of internal power
Selects resistance ratio of the internal resistor used in the internal voltage regulator. See voltage regulator section in
COD = 0: normal direction ( COM0 COM79 )
COD = 1: reverse direction ( COM79 COM0 )
