Notes:
1. The measurement condition is VCC = 1.8 to 5.5 V and Topr =
20 to 85 °C (N version)/40 to 85 °C (D version).
2. Select the voltage detection level with bits VDSEL0 and VDSEL1 in the OFS register.
3. Necessary time until the voltage detection circuit operates when setting to 1 again after setting the VCA25 bit in the VCA2
register to 0.
4. Time until the voltage monitor 0 reset is generated after the voltage passes Vdet0.
Notes:
1. The measurement condition is VCC = 1.8 to 5.5 V and Topr =
20 to 85 °C (N version)/40 to 85 °C (D version).
2. Select the voltage detection level with bits VD1S0 to VD1S3 in the VD1LS register.
3. Time until the voltage monitor 1 interrupt request is generated after the voltage passes Vdet1.
4. Necessary time until the voltage detection circuit operates when setting to 1 again after setting the VCA26 bit in the VCA2
register to 0.
