5.14.17Coefficient Write Control Register

Coefficients for user-defined EQ, Mixing, Scaling, and Bass Management are handled internally in the STA320

are dedicated to this function.

One contains a coefficient base address, five sets of three store the values of the 24-bit coefficients to be written

or that were read, and one contains bits used to control the write/read of the coefficient(s) to/from RAM. The

following are instructions for reading and writing coefficients.
