Coefficient b0 data register bits 23:16 (addr 0x23)
Coefficient b0 data register bits 15:8 (addr 0x24)
Coefficient b0 data register bits 7:0 (addr 0x25)
Coefficient write control register (addr 0x26)
Coefficients for EQ, mix and scaling are handled internally in the STA326 via RAM. Access
to this RAM is available to the user via an I
are dedicated to this function. First register contains the coefficient base address, five sets
of three registers store the values of the 24-bit coefficients to be written or that were read,
and one contains bits used to control the read or write of the coefficient (s) to RAM. The
following are instructions for reading and writing coefficients.
