Queued Analog-to-Digital Converter (QADC)
When externally multiplexed mode is selected, the QADC automatically drives the MA 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 16 externally multiplexed
channels appear to the conversion queues as directly connected signals. User software simply puts the
channel number of externally multiplexed channels into CCWs.
