NOTES:
1. The measurement condition is V
CC = 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 V
det2 > Vdet1.
NOTES:
1. The measurement condition is V
CC = 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 V
det1.
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 V
det2 > Vdet1.
