The MULT bit in ADCTL determines whether one or four channels are
converted. When MULT = 0, one channel is converted. The selected
channel is sampled and the conversion results are written to ADR1; the
same channel is sampled again, and the conversion results are stored
in ADR2, and so on. In continuous mode, the same channel continues to
be sampled and converted. Setting the MULT bit converts four different
channels; each result register contains the conversion result of a
different channel. In continuous mode, the same four channels are
converted in each sequence.
ADCTL bits [3:0] select the particular channel(s) to be converted. See
