NOTES:
1.
The measurement condition is VCC = 2.2 to 5.5 V and Topr =
20 to 85°C (N version) / 40 to 85°C (D version).
2.
Necessary time until the voltage detection circuit operates when setting to 1 again after setting the VCA25 bit in the VCA2
register to 0.
NOTES:
1.
The measurement condition is VCC = 2.2 to 5.5 V and Topr =
20 to 85°C (N version) / 40 to 85°C (D version).
2.
Time until the voltage monitor 1 interrupt request is generated after the voltage passes Vdet1.
3.
Necessary time until the voltage detection circuit operates when setting to 1 again after setting the VCA26 bit in the VCA2
register to 0.
4.
This parameter shows the voltage detection level when the power supply drops.
The voltage detection level when the power supply rises is higher than the voltage detection level when the power supply
drops by approximately 0.1 V.
NOTES:
1.
The measurement condition is VCC = 2.2 to 5.5 V and Topr =
20 to 85°C (N version) / 40 to 85°C (D version).
2.
Time until the voltage monitor 2 interrupt request is generated after the voltage passes Vdet2.
3.
Necessary time until the voltage detection circuit operates after setting to 1 again after setting the VCA27 bit in the VCA2
register to 0.
