When the external multiplexed mode is selected, the QADC automatically creates the
MA[2:0] open drain output signals from the channel number in each CCW. The QADC
also converts the proper input channel (ANw, ANx, ANy, and ANz) by interpreting the
CCW channel number. As a result, up to 32 externally multiplexed channels appear to
the conversion queues as directly connected signals. Software simply puts the chan-
nel number of an externally multiplexed channel into a CCW.
Figure 8-3 shows that MA[2:0] may also be analog or digital input pins. When external
multiplexing is selected, none of the MA[2:0] pins can be used for analog or digital in-
puts. They become multiplexed address outputs.
