Transition Time to Suspend
NOTES:
1.
The measurement condition is VCC = 2.7 V to 5.5 V and Topr = -40
°C to 85 °C.
2.
Necessary time until the voltage detection circuit operates when setting to 1 again after setting the VCA26 bit in the VCA2
register to 0.
3.
Ensure that Vdet2 > Vdet1.
NOTES:
1.
The measurement condition is VCC = 2.7 V to 5.5 V and Topr = -40
°C to 85 °C.
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 when setting to 1 again after setting the VCA27 bit in the VCA2
register to 0.
4.
Ensure that Vdet2 > Vdet1.
