7.4.2 Post-scale link
Bit R/W RST

Table 115. Post-scale link
Name
Description
0: Each channel uses individual post-scale value
PSL
1: Each channel uses channel 1 post-scale value
7.4.3
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.
Biquad coefficient link

Description
BQL
0: Each channel uses coefficient values
1: Each channel uses channel 1 coefficient values
7.4.4
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.
