12.18 Electronic Volume (Two-Byte Command)
This command can be used to control the LCD drive voltage V
LC1
(which is output from the on-chip LCD power
supply’s voltage regulator circuit) to regulate the darkness of the LCD contents.
This command is a two-byte command that is used in a pair with the electronic volume mode set command and the
electronic volume register set command, so be sure to use both commands consecutively.
12.18.1 Electronic volume mode set command (first byte)
Once this command is input, the electronic volume register set command becomes valid. And once the electronic
volume mode has been set, any command other than the electronic volume register set command cannot be used.
This restriction is cleared once data has been set to the register by the electronic volume register set command.
