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.
