6.6.3 Functional Mode (FM)
Default = 00
00 - Single-Speed Mode (4 to 50 kHz sample rates)
01 - Double-Speed Mode (50 to 100 kHz sample rates)
10 - Quad-Speed Mode (100 to 200 kHz sample rates)
11 - Direct Stream Digital Mode
Function:
Selects the required range of input sample rates or DSD Mode. All DAC pairs are required to be set to the
same functional mode setting before a speed-mode change is accepted. When DSD Mode is selected for
any channel pair, all pairs switch to DSD Mode.
6.7 Volume Control (Addresses 07h, 08h, 0Ah, 0Bh, 0Dh, 0Eh)
Note: These six registers provide individual volume and mute control for each of the six channels.
The values for “xx” in the bit fields above are as follows:
Register address 07h - xx = A1
Register address 08h - xx = B1
Register address 0Ah - xx = A2
Register address 0Bh - xx = B2
Register address 0Dh - xx = A3
Register address 0Eh - xx = B3
6.7.1 Mute (MUTE)
Default = 0
0 - Disabled
1 - Enabled
Function:
The Digital-to-Analog converter output will mute when enabled. The quiescent voltage on the output will
be retained. The muting function is affected, similarly to attenuation changes, by the Soft and Zero Cross
bits. The MUTE pins will go active during the mute period according to the MUTEC bits.
