This register is utilized to program the digital output attenuation for the Left output channel of the
corresponding SRC section.
Register defaults to 00h, or 0dB (unity gain).
Output Attenuation (dB) = N

This register is utilized to program the digital output attenuation for the Right output channel of the
corresponding SRC section. When the TRACK bit in Control Register 1 is set to 1, the Left Channel
attenuation setting will also be used to set the Right Channel attenuation.
Register defaults to 00h, or 0dB (unity gain).
Output Attenuation (dB) = N

The contents of Register 6 and Register 7 indicate the input-to-output sampling ratio, and can be used to
determine either the input or output sampling rates when one of the two rates is known.
Bits SRI[4:0] comprise the integer portion of the input-to-output sampling ratio.
Bits SRF[10:0] comprise the fractional portion of the input-to-output sampling ratio.
The contents of Register 6 and Register 7 are updated when Register 6 is read. Register 6 must always be
read first in order to obtain the latest ratio data for both registers.
