denote the expected digital code that should be generated by the
special conversion for 8-bit resolution.
These bits select the analog input channel(s).
coding used to select the various analog input channels. In the case
of single channel scans (MULT=0), this selection code specifies the
channel for conversion. In the case of multi-channel scans (MULT=1),
this selection code represents the first channel to be examined in the
conversion sequence. Subsequent channels are determined by
incrementing the channel selection code; selection codes that reach
the maximum value wrap around to the minimum value.
Note that for special conversion mode, bits CC/CB/CA have a
different function. Instead of specifying the analog input channel, they
identify which special channel conversion is to take place. (See
19-8.) A summart of the channels converted and the associated result
locations for multiple channel scans can be found in
