Coefficient write/read control register
Coefficients for user-defined EQ, mixing, scaling, and bass management are handled
internally in the STA350Bx 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.
Three different RAM banks are embedded in the STA350Bx. The three banks are managed
in paging mode using EQCFG register bits. They can be used to store different EQ settings.
For speaker frequency compensation, a sampling frequency independent EQ must be
implemented. Computing three different coefficients set for 32 kHz, 44.1kHz, 48 kHz and
downloading them into the three RAM banks, it is possible to select the suitable RAM block
depending on the incoming frequency with a simple I2C write operation in register 0x31.
