SCAN — Continuous Conversion Sequence Mode
1 = Perform conversion sequences continuously.
0 = Perform a conversion sequence and return to idle mode.
The scan mode bit controls whether or not conversion sequences are
performed continuously or only once.
MULT — Multi-Channel Sample Mode
1 = Sample across many channels.
0 = Sample only the specified channel.
When MULT is 0, the ATD sequence controller samples only from the
specified analog input channel for an entire conversion sequence.
The analog channel is selected by channel selection code (control
bits CC/CB/CA located in ATDCTL5). When MULT is 1, the ATD
sequence controller samples across channels. The number of
