Vdet0 cannot be monitored.
Once the following settings are made, the comparison result of voltage monitor 1 can be monitored by the
VW1C3 bit in the VW1C register after td(E-A) has elapsed (refer to 33. Electrical Characteristics).
(1) Set bits VD1S3 to VD1S0 in the VD1LS register (voltage detection 1 detection voltage).
(2) Set the VCA26 bit in the VCA2 register to 1 (voltage detection 1 circuit enabled).
Once the following settings are made, the comparison result of voltage monitor 2 can be monitored by the
VCA13 bit in the VCA1 register after td(E-A) has elapsed (refer to 33. Electrical Characteristics).
• Set the VCA27 bit in the VCA2 register to 1 (voltage detection 2 circuit enabled).
