voltage
3.3 [V] or higher
Rest voltage 2.8 [V]
The VBatt circuit operates at the edge
where the reset voltage becomes Hi.
(At this time, the output transistors are
set on and the load is put on; If this
voltage is 3.3 [V] or higher, the VBatt
circuit operates, and if it is lower than
3.3 [V], it does not start up.
