Coefficients for EQ and Bass Management are handled internally in the STA309A 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 of the coefficient(s) to RAM. The

following are instructions for reading and writing coefficients.
