ON/OFF control of the +5SPC power supply
(L = ON / H = OFF: for reduction of standby power)
Fixed at Low usually
The standby power is reduced (MCUSleep) by setting at Hi after the
procedure required for the standby setting is completed
When changing to the Standby mode, set at Hi after the ending
procedure is completed
