Multiplier Clock Frequency Select (2-byte command)
This command selects the multiplier clock frequency of the 1^st and 2^nd voltage multiplier circuits. This command is
a 2-byte command to be used together with the multiplier clock frequency select mode set command and the
multiplier clock frequency select register set command. So, be sure to set the both commands continuously.
• Multiplier Clock Frequency Select mode set (Write)
When this command is input, the multiplier clock frequency select register set command becomes valid. Once the
multiplier clock frequency select mode is selected, any command other than the multiplier clock frequency select
register set command cannot be used. This status is released when any data is stored in the register by the multiplier
clock frequency select register set command.
