Vdet0 cannot be monitored.
Make the following settings and wait for td(E-A) (refer to 28. Electrical Characteristics). After that, the
comparison result from voltage monitor 1 can be monitored with the VW1C3 bit in the VW1C register.
(1) Set bits VD1S0 to VD1S3 in the VD1LS register to select the detection voltage for voltage detection 1.
(2) Set the VCA26 bit in the VCA2 register to 1 (voltage detection 1 circuit enabled).
Make the following settings and wait for td(E-A) (refer to 28. Electrical Characteristics). After that, the
