Once the following settings are made, the comparison result of comparator A1 can be monitored by the VW1C3
bit in the VW1C register after td(E-A) has elapsed (refer to 34. Electrical Characteristics).
(1) Set the VCA21 bit in the VCA2 register to 1 (LVREF pin input voltage).
(2) Set the VCA22 bit in the VCA2 register to 1 (LVCMP1 pin input voltage).
(3) Set the VCA26 bit in the VCA2 register to 1 (comparator A1 circuit enabled).
Once the following settings are made, the comparison result of comparator A2 can be monitored by the VCA13
bit in the VCA1 register after td(E-A) has elapsed (refer to 34. Electrical Characteristics).
(1) Set the VCA23 bit in the VCA2 register to 1 (LVREF pin input voltage).
(2) Set the VCA24 bit in the VCA2 register to 1 (LVCMP2 pin input voltage).
(3) Set the VCA27 bit in the VCA2 register to 1 (comparator A2 circuit enabled).
