BIASCON is a special function register (SFR) to control the bias generation circuit.
[Description of Bits]
Initial value
BIASCON
The BSON bit is used to control the operation of the bias generation circuit.
When BSON is set to “1”, the bias generation circuit generates the LCD drive voltages (VL1 to VL4).
The BSN2 to BSN0 bits are used to select a clock for multiplying the bias voltage in the bias generation circuit.
LSCLK to 1/128LSCLK can be selected.
The BSEL bit is used to set the bias in the bias generation circuit.
1/3 bias or 1/4 bias can be selected.
