CD, CC, CB, and CA — Channel Select for Conversion
Shaded bits are “don’t care” if MULT = 1 and the entire block of four or eight channels make up
a conversion sequence. When MULT = 0, all four bits (CD, CC, CB, and CA) must be specified
and a conversion sequence consists of four or eight consecutive conversions of the single spec-
ified channel.
