+5SPC power ON/OFF control (L=ON/H=OFF : to save power during standby)
Normally fixed to Low. Power used in standby state is reduced by setting to HI
after completion of the process accompanying standby state (MCU Sleep)
(When set to HI, expansion port or expansion A/D does not operate.)
Keep [HionFix] until Power ON input is executed when using ACIN, MCUSleep
When power is turned ON, use min20msec after setting [SPC] LowAct as the
time for setting the expansion port
