Time delay until Suspend
NOTES:
1. The measurement condition is VCC = 2.2 V 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 V 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.
