Command Register 1
(Continued)
If SCANEN* is cleared, analog channels MA<3..0>
through channel 0 are sampled. Sampling order,
whether from channel 0 to MA<3..0> or from
MA<3..0> to channel 0, is determined by the
SCANORDER bit in Command Register 2. If
SCANEN* is set, a single analog channel specified by
MA<3..0> is sampled during the entire data
acquisition operation. See the
Programming Multiple
A/D Conversions with Channel Scanning
section later
in this appendix for the correct sequence involved in
setting the SCANEN* bit.
