(18) The Electronic Volume (Double Byte Command)
This command makes it possible to adjust the brightness of the liquid crystal display by controlling the liquid crystal
drive voltage V
through the output from the voltage regulator circuits of the internal liquid crystal power supply.

This command is a two byte command used as a pair with the electronic volume mode set command and the electronic
volume register set command, and both commands must be issued one after the other.
• The Electronic Volume Mode Set
When this command is input, the electronic volume register set command becomes enabled. Once the electronic volume
mode has been set, no other command except for the electronic volume register command can be used. Once the
electronic volume register set command has been used to set data into the register, then the electronic volume mode is
released.
