Coefficient write/read control register
Coefficients for user-defined EQ, mixing, scaling, and bass management are handled
internally in the STA382BW via RAM. Access to this RAM is available to the user via an I2C
register interface. A collection of I2C registers is 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.
Note:
The read and write operation on RAM coefficients works only if the LRCKI pin is switching.
