Note: Because this LSI has temperature gradient, V1 rises at lower temperatures. When using V1 gain
of 6 times, adjust the built-in electronic potentiometer so that V1 does not exceed 18 V.
Electronic potentiometer (2-byte command)
This command is used for controlling the LCD drive voltage V1 output by the voltage adjustment circuit of the
internal LCD power supply and for adjusting the intensity of the LCD display.
This is a two-byte command consisting of the Electronic potentiometer mode set command and the Electronic
potentiometer register set command, both of which should always be issued successively as a pair.
• Electronic potentiometer mode set (Write)
When this command is issued, the electronic potentiometer register set command becomes effective.
Once the electronic potentiometer mode is set, it is not possible to issue any command other than the Electronic
potentiometer register set command. This condition is released after data has been set in the register using the
Electronic potentiometer register set command.
