Hi Sotoshi-san,
First you must choose a processing block that supports biquad filters. An example would be PRB_R2. You can see on Table 6 on Page 33 of the datasheet, that PRB_R2 supports 5 Biquads. You can select PRB_R2 in Register 61 on Page 0.
Next you can Map the biquad coefficients from your text file above to the proper registers. You can see these on Table 8 on Page 37 of the datasheet. So for instance, Your N0 value is 0x7C7D, this would be written to Page 4 Register 14 and 15 for the Left channel and Page 4 Register 78 and 79 for the Right Channel. Then you just continue through Biquad A, B and C on table 8.
The coefficients must be written before the ADC is powered up in register 36 on page 0.
If you have a script that you are testing, feel free to forward it and I can take a look.
Best Regards,
dave
