1. The measurement condition is V
2. Time until the voltage monitor 1 interrupt request is generated after the voltage passes V
3. Necessary time until the voltage detection circuit operates when setting to 1 again after setting the VCA26 bit in the VCA2
4. This parameter shows the voltage detection level when the power supply drops.
