Number of Conversions per Sequence
Table 19-7. Result Register Assignment for Different Conversion
SCAN — Continuous Conversion Sequence Mode
The result register assignments made to a conversion sequence follow
a few simple rules. Normally, the first result is placed in the first register;
the second result is placed in the second register, and so on.

lengths that are normally made. If FIFO mode is used, the result
register assignments differ. The results are placed in consecutive
registers between conversion sequences; the result register mapping
wraps around when the end of the register file is reached.
The scan mode bit controls whether or not conversion sequences are
performed continuously or not. If this control bit is 0, a write to control
register 4 or 5 will initiate a conversion sequence; the conversion
sequence will be executed; the sequence complete flag (SCF) will be
set, and the module will return to idle mode. In this mode, the module
remains powered up but no conversions are performed; the module
waits for the next conversion sequence to be initiated.
If this control bit is 1, a single conversion sequence initiation will result
in a continuously executed conversion sequence. When a conversion
sequence completes, the sequence complete flag (SCF) is set and a
new sequence is immediately begun. The conversion mode
characteristics of each sequence are identical. If a new conversion
