SCAN — Enable Continuous Channel Scan
MULT — Enable Multichannel Conversion
CD, CC, CB, and CA — Channel Select for Conversion
S8CM
When a conversion sequence is initiated by a write to the ATDCTL
register, the user has a choice of performing a sequence of four (or
eight, depending on the S8CM bit) conversions or continuously
performing four (or eight) conversion sequences.
