STA323W
8.6.17Coefficient Write Control Register (Address 26h)
Coefficients for EQ, Mix and Scaling are handled internally in the STA323W via RAM. Access to this RAM
is available to the user via an I
2
C register interface. A collection of I
2
C registers are dedicated to this func-
tion. 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.
8.7 Reading a coefficient from RAM
■

2
C register 26h
■
read top 8-bits of coefficient in I
2
C address 17h
■
read middle 8-bits of coefficient in I
2
C address 18h
■
read bottom 8-bits of coefficient in I
2
C address 19h
8.8 Reading a set of coefficients from RAM
■
write 8-bits of address to I
2
C register 16h
■

2
C address 17h
■
read middle 8-bits of coefficient in I
2
C address 18h
■
read bottom 8-bits of coefficient in I
2
C address 19h
■
read top 8-bits of coefficient b2 in I
2
C address 1Ah
■

2
C address 1Ch
■
read top 8-bits of coefficient a1 in I
2
C address 1Dh
■
read middle 8-bits of coefficient a1 in I
2
C address 1Eh
■

2
C address 21h
■
read bottom 8-bits of coefficient a2 in I
2
C address 22h
■
read top 8-bits of coefficient b0 in I
2
C address 23h
■
read middle 8-bits of coefficient b0 in I
2
C address 24h
■
read bottom 8-bits of coefficient b0 in I
2
C address 25h
8.9 Writing a single coefficient to RAM
■
write 8-bits of address to I
2
C register 16h
■
