Figure 5.2

Time delay until Suspend

NOTES:

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).

Necessary time until the voltage detection circuit operates when setting to 1 again after setting the VCA25 bit in the VCA2

NOTES:

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).

Time until the voltage monitor 1 interrupt request is generated after the voltage passes Vdet1.

Necessary time until the voltage detection circuit operates when setting to 1 again after setting the VCA26 bit in the VCA2

NOTES:

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).

Time until the voltage monitor 2 interrupt request is generated after the voltage passes Vdet2.

Necessary time until the voltage detection circuit operates after setting to 1 again after setting the VCA27 bit in the VCA2
