Coefficients for user-defined EQ, Mixing, Scaling, and Bass Management are handled internally in the STA320
via RAM. Access to this RAM is available to the user via an I2C register interface. A collection of I2C registers
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.
