The measurement condition is VCC = 1.8 V 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 V 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.
