6.2.3 Functional Mode (FM) Bits 1-0
Default = 00
00 - Auto speed mode detect
01 - Single-Speed Mode (4 to 50 kHz sample rates)
10 - Double-Speed Mode (50 to 100 kHz sample rates)
11 - Quad-Speed Mode (100 to 200 kHz sample rates)
Function:
Selects the required range of input sample rates or DSD Mode.
6.3 Volume Mixing and Inversion Control - Register 03h
6.3.1 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.
6.3.2 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.
6.3.3 Invert Signal Polarity (Invert_B) Bit 5
Function:
When set to 1, this bit inverts the signal polarity of channel B.
When set to 0 (default), this function is disabled.
