9.8
Data format
A 3-bit value to select the data format.
Table 27 Data format selection
9.9
DAC power control
A 1-bit value to disable the DAC to reduce power
consumption. The DAC power-off is not recommended
when the DAC outputs are DC loaded.
Table 28 DAC power control
9.10
Input oversampling rate
A 2-bit value to select the oversampling rate of the input
signal (see Table 32). In the quad speed input rate, care
must be taken that the input signal is smaller than
5.67 dB (FS).
9.11
DAC polarity
A 1-bit value to control the DAC polarity.
Table 29 Polarity control of DAC
9.12
DAC mixing position switch
A 1-bit value to select the mixing position of the ADC signal
in the DAC.
Table 30 DAC mixing position switch
9.13
DAC mixer
A 1-bit value to enable the digital mixer of the DAC.
