6.16.1 DSP bypass
Setting the DSPB bit bypasses the EQ function of the STA382BW.
6.16.2 Post-scale link
Post-scale functionality can be used for power-supply error correction. For multi-channel
applications running off the same power supply, the post-scale values can be linked to the
value of channel 1 for ease of use and in order to update the values faster.
6.16.3 Biquad coefficient link
For ease of use, all channels can use the biquad coefficients loaded into the channel 1
coefficient RAM space by setting the BQL bit to 1. Therefore, any EQ updates only have to
be performed once.
