This command causes some of the internal status of the chip to be initialized:
This command sets the scan direction of the COM output allowing layout flexibility in LCD
module assembly.
This command turns on/off the various power circuits associated with the chip. There are three
power relating sub-circuits could be turned on/off by this command.
Internal voltage booster is used to generate the highest positive voltage supply internally from
the voltage input (V
Internal regulator is used to generate the LCD driving voltage.
Output op-amp buffer is the internal divider for dividing the different voltage levels (V

driver if this circuit is turned off.
This command is to enable any one of the eight internal resistor (IRS) settings for different
regulator gains when using internal regulator resistor network. The Contrast Control Voltage
