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 con-
sists of four or eight consecutive conversions of the single specified chan-
nel.
