Analog Output Register Group
Note
The analog output register group is not valid for the PCI-6023E, PCI-6032E and
PCI-6033E.
The four registers making up the Analog Output Register Group access the two analog output
channels, the analog output FIFO, and the analog output configuration. Data can be
transferred to the DACs in one of two ways. Data can be directly sent to the DACs from the
host computer, or buffered from the host by the DAC data FIFO.
