Coefficient write/read control register
Coefficients for user-defined EQ, mixing, scaling, bass management and STCompressorTM
(see Section 4.2) are handled internally in the STA381BWS 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.
Note:
The read and write operation on RAM coefficients works only if LRCKI (pin 29) is switching.
