This read/write register is used to transfer EQ biquad coefficients into memory.

The register data is transferred to, or retrieved from, the address pointed to by the BCA bits in the EQ control register (0x60).

Data will be written to memory only if the EQM bit (Register 0x60, Bit 15) is asserted.

CFD[15:0]

Coefficient Data. The biquad coefficients are fixed-point format values with 16 bits of resolution. The CFD15 bit is the MSB

and the CFD0 bit is the LSB.
