The heart of the QADC is its conversion command word (CCW) queues. This is where the module is
programmed to convert a particular channel according to a particular requirement. The queues are created
by writing CCWs into the CCW table in the register memory. The queues are controlled by the three
control registers, and their status can be read from the two status registers. As conversions are completed
the digital value is written into the result word table.
word table.
13.2.5
The QADC can use from one to four 8-input external multiplexer chips to expand the number of analog
signals that may be converted. The externally multiplexed channels are automatically selected from the
