Volume Control (Address 0Bh, 0Ch, 0Eh, 0Fh, 11h, 12h, 14h, 15h)
PCM Clock Mode (Address 16h)
Default = 00h (0 dB)
Function:
The Digital Volume Control registers allow independent control of the signal levels in 1/2 dB increments
from 0 to -127.5 dB. Volume settings are decoded as shown in
mented as dictated by the Soft and Zero Cross bits in the Power and Muting Control register. Note that
the values in the volume setting column in
by taking the decimal value of the volume register and multiplying by 6.02/12.
Function:
When set to 1, the MCLKDIV bit enables a circuit which divides the externally applied MCLK signal by 2
prior to all other internal circuitry.
When set to 0 (default), MCLK is unchanged.
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 0Bh - xx = A1
Register address 0Ch - xx = B1
Register address 0Eh - xx = A2
Register address 0Fh - xx = B2
Register address 11h - xx = A3
Register address 12h - xx = B3
Register address 14h - xx = A4
Register address 15h - xx = B4
