1. The measurement condition is V
2. Time until the voltage monitor 2 interrupt request is generated after the voltage passes V
3. Necessary time until the voltage detection circuit operates after setting to 1 again after setting the VCA27 bit in the VCA2
1. The measurement condition is T
2. To use the power-on reset function, enable voltage monitor 0 reset by setting the LVDAS bit in the OFS register to 0.
