Volume Mixing and Inversion Control - Register 03h
De-Emphasis Control (DEM[1:0]) Bits 3-2
Default = 0
00 - No De-emphasis
01 - 44.1 kHz De-emphasis
10 - 48 kHz De-emphasis
11 - 32 kHz De-emphasis
Function:
Selects the appropriate digital filter to maintain the standard
15 μs/50 μs digital de-emphasis filter response at 32, 44.1
or 48 kHz sample rates. (See

Functional Mode (FM[1:0]) Bits 1-0
Default = 00
00 - Auto speed mode detect
01 - Single-Speed Mode (30 to 54 kHz sample rates)
10 - Double-Speed Mode (50 to 108 kHz sample rates)
11 - Quad-Speed Mode (100 to 216 kHz sample rates)
Function:
Selects the required range of input sample rates or auto speed mode.
Channel A Volume = Channel B Volume (VOLB=A) Bit 7
Function:
When set to 0 (default), the AOUTA and AOUTB volume levels are independently controlled by the A and
the B Channel Volume Control Bytes.
When set to 1, the volume on both AOUTA and AOUTB are determined by the A Channel Attenuation and
Volume Control Bytes, and the B Channel Bytes are ignored.
Invert Signal Polarity (INVERT_A) Bit 6
Function:
When set to 1, this bit inverts the signal polarity of channel A.
When set to 0 (default), this function is disabled.
This function is only available for Left Justified, Right Justified 16, and Right Justified 24 data formats.
