Note:
* The asterisk ( ) indicates that the power supply voltage detection unit characteristics are standards in
the transient power on/off states. However, for convenience the detection voltage is taken to be the
value of V0 when V0 in measurement circuit 2 is varied and the pin 6 output state is switched from off
to on.
