When set, the
module configures the channel and
reads the channel input before
setting bit 11 in the status word. If
you change the configuration word,
the status word must reflect the
change before new data is valid. If
you clear the configuration word, the
module clears channel and status
words. For a new configuration word,
channel data and status words
remain cleared until the module sets
this bit (11) in the status word.
