1. The voltage detection level must be selected with bits VDSEL0 and VDSEL1 in the OFS register.
2. Time until the voltage monitor 0 reset is generated after the voltage passes V
3. Necessary time until the voltage detection circuit operates when setting to 1 again after setting the VCA25 bit in the VCA2
register to 0.
