DA_POL_INV
DAC polarity control.
A 1-bit value to control the signal polarity of the DAC
output signal. When set to logic 0, the DAC output is not inverted. When set to
logic 1, the DAC output is inverted. Default value 0.
Sample frequency range selection.
A 1-bit value to select the sampling
frequency range. When set to logic 0, the frequency range is approximately
8 to 50 kHz; the frequency range in modes 6 and 7 is 8 to 28 kHz. When set
to logic 1, the frequency range is approximately 28 to 55 kHz. Default value 1.

DAC input selection.
A 2-bit value to select the data and clock sources for
the DAC and the input source for the PLL. The DAC data source is either the
IEC 60958 input or the digital input interface. Default value 10; see Table 45.
