2. Setting volume values
Optional attenuation data is input through the DATA, CK and STB terminals.
Data consists of 18 bits as follows
(1) Serial data format
SC9260
(2)Chip select code (C1~C4)
Chip select code is set to use serial bus line in common with other ICs. Data C2, C3, C4 is fixed 0, 1, 1 in
SC9260. When level of CS input pin (7 pin) correspond to C1 bit, data is valid.
(3)L is left-channel select data; R is right-channel select data (L/R)
When L=1, left-channel volume is set; when R=1, right-channel volume is set.
(When R=L=1, both channel volume are set simultaneously).
(4)LD is loudness setting data
When LD=”0”, loudness is OFF (LS1=OFF, LS2=ON)
When LD=”1”, loudness is ON (LS1=ON, LS2=OFF)
(5)Volume setting data (D1~D6)
