Notes:

1. Select the voltage detection level with bits VDSEL0 and VDSEL1 in the OFS register.

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

3. Time until the voltage monitor 0 reset is generated after the voltage passes Vdet0.

Notes:

1. Select the voltage detection level with bits VD1S0 to VD1S3 in the VD1LS register.

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

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