DSP bypass
Table 30.
Setting the DSPB bit bypasses the EQ functionality of the STA559BWQS.
Post-scale link
Table 31.
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 update the values faster.
Biquad coefficient link
Table 32.
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.
