The HPM register is the power control for the power supply circuit for liquid crystal
drive.
HPM= “H”: High power mode
HPM= “L”: Normal mode
BF1~BF0: The operating frequency in the booster is selected. When the boosting
frequency is high, the driving ability of booster become high, but the current
consumption is increased. Adjust the boosting frequency considering the external
capacitors and the current consumption.
