Vdet0 cannot be monitored.
Set the VCA26 bit in the VCA2 register to 1 (voltage detection 1 circuit enabled). After td(E-A) has elapsed
(refer to 21. Electrical Characteristics), Vdet1 can be monitored by the VW1C3 bit in the VW1C register.
Set the VCA27 bit in the VCA2 register to 1 (voltage detection 2 circuit enabled). After td(E-A) has elapsed
(refer to 21. Electrical Characteristics), Vdet2 can be monitored by the VCA13 bit in the VCA1 register.
