8.7.5.1 Conversion Parameters
8.7.5.2 Conversion Modes
8-8
Single or multiple channel conversion
Table 8-5
Conversion modes are defined by the state of the SCAN, MULT, and S8CM bits in
ADCTL1.
The following paragraphs describe each type of conversion mode:
Mode 0 — A single four-conversion sequence is performed on a single input channel
specified by the value in CD:CA. Each result is stored in a separate result register
(RSLT0 to RSLT3). The appropriate CCF bit in ADCSTAT is set as each register is
filled. The SCF bit in ADCSTAT is set when the conversion sequence is complete.
Mode 1 — A single eight-conversion sequence is performed on a single input channel
specified by the value in CD:CA. Each result is stored in a separate result register
(RSLT0 to RSLT7). The appropriate CCF bit in ADCSTAT is set as each register is
filled. The SCF bit in ADCSTAT is set when the conversion sequence is complete.

The value of the channel selection field (CD:CA) in ADCTL1 determines
which multiplexer inputs are used in a conversion sequence. There are
16 possible inputs. Seven inputs are external pins (AN[6:0]), and nine
are internal.
A conversion sequence consists of either four or eight conversions. The
number of conversions in a sequence is determined by the state of the
S8CM bit in ADCTL1.
Conversion can be limited to a single sequence or a sequence can be
performed continuously. The state of the SCAN bit in ADCTL1 deter-
mines whether single or continuous conversion is performed.
Conversion sequence(s) can be run on a single channel or on a block of
four or eight channels. Channel conversion is controlled by the state of
the MULT bit in ADCTL1.
