Time delay until Suspend
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.
