Default value: 00 00 16 to 24 bits, I2S (default) 01 16 to 24 bits, left-justified 10 24 bits, right-justified 11 16 bits, right-justified DM12: De-Emphasis Filter Enable for DAC12 This bit enables the DAC12 de-emphasis filter. The frequency can be selected by setting bits DF12[1:0] of Register 45. Default value: 0 0 Disable (default) 1 Enable DF12[1:0]: De-Emphasis Filter Sampling Rate Selection for DAC12 A digital de-emphasis filter is in front of the interpolation filter. One of three de-emphasis filters can be selected corresponding to the sampling rate: 32 kHz, 44.1 kHz, or 48 kHz. Default value: 00 00 44.1 kHz (default) 01 48 kHz 10 32 kHz 11 Reserved REG HEX DESCRIPTION B7 B6 B5 B4 B3 B2 B1 B0 46 2Eh Power up/down, oversampling rate control for DAC12 PD12 RSV OV12[1:0] ZR12 RSV RSV RSV PD12: Power Up/Down Control for DAC12 This bit controls the power up/down for DAC12, including the interpolation filter. Default value: 1 0 Power up 1 Power down (default) OV12[1:0]: Oversampling Rate Control for DAC12 These bits are used to control the oversampling rate of the DAC12 delta-sigma modulator.
