The 12 analog input pins are divided into two channel sets and two groups, with analog input pins
0 to 7 (AN0 to AN7) comprising channel set 0, analog input pins 8 to 11 (AN8 to AN11)
comprising channel set 1, analog input pins 0 to 3 and 8 to 11 (AN0 to AN3, AN8 to AN11)
comprising group 0, and analog input pins 4 to 7 (AN4 to AN7) comprising group 1.
