• +5SPC power ON/OFF control
Hi: ON, Low: OFF, To save stand-by power
• Usually fixed at Hi setting when the power is turned on
By setting to Low after processes required for stand-by are finished,
the stand-by power is reduced (MCUSleep)
When shifting to Stand-by state,
set to Low after the end procedure is completed
