(At the time of reset: {BF1, BF0, DIS} = 0H; read address: 5H)
DIS: is the register that controls the capacitors (connected between the power supply
V0-V4 for the LCD drive voltage and VSS) voltage discharged to VSS.
DIS = “0”: Disable
DIS = “1”: Enable
BF1~BF0: The operating frequency in the booster is selected. When the boosting
frequency is high, the driving ability of the booster become high, but the current
consumption is increased. You must take the external capacitors and the current
consumption into consideration when adjusting the boosting frequency.
