Volume Control (addresses 07h, 08h, 0Ah, 0Bh, 0Dh, 0Eh)
Note:
These eight registers provide individual volume and mute control for each of the eight 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
Register address 10h - xx = A4
Register address 11h - xx = B4
5.7.1
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 bit.
5.7.2
Volume Control (xx_VOL)
Default = 0 (No attenuation)
Function:
The Digital Volume Control registers allow independent control of the signal levels in 1 dB increments from
0 to -127 dB. Volume settings are decoded as shown in Table 8. The volume changes are implemented
as dictated by the Soft and Zero Cross bits. All volume settings less than -127 dB are equivalent to enabling
the MUTE bit.
