12. LCD Bias
These commands select the bias ratio for the voltages required for LCD drive.
These commands form a 2-byte command pair: the Electronic Potentiometer Mode Set command and the Electronic
Potentiometer Register Set command. These two commands must be issued consecutively.
LCD Bias Mode Set
When this command is issued, the LCD Bias Register Set command is enabled. Once the electronic potentiometer mode
is set, no command other than the LCD Bias Register Set command can be used. This state is cleared after data is stored
into the register with the LCD Bias Register Set command.
This command is cleared when a reset input occurs or when a reset command is issued.
LCD Bias Register Set
Stores 3 bits of data into the LCD bias register to select one of 6 bias values.
LCD bias mode is cleared after the LCD bias register is set by issuing this command.
The bias is set to 1/10 if a value other than those listed above is used for D2 to D0.
