+5SPC Power supply ON/OFF control. (L=ON/H=OFF: Standby power
requirement reduction sake) / Usually, Low fixes is standby power
requirement reduction (MCUSleep) by making it HI, after the processing
accompanying standby is completed. (An extended port and extended
A/D do not operate at the time of HI.) / The time of AC IN and MCUSleep,
please hold HighFix until there is a Power On input.
