SERIAL DATA CODE The data code is consists by L, R, D1~D4, LD, C1~C4 (totally 13 bits), at the end of the code there needs a high strobe pulse to confirm the data code is validity. LR D1 D2 D3 D4 D5 D6 LD C1 C2 C3 C4 CK DAT A STB CHIP SELECTION (C1~C4) The Chip Selection code C1 is depending on the states of the CS pin, the CS pin in low state means the C1 bit=0; and the CS pin in high state means the C1 bit=1. Ignore what states of the CS pin the C2, C3 and C4 bit is presets to the state 0, 1, 1. CS C1 C2 C3 C4 “1” 1 0 1 1 “0” 0 0 1 1 LEFT AND RIGHT CHANNEL CONTROL CODE In the DATA code, the “L” bit is for left channel and the “R” is for right channel is selected. If the “L” bit is 1 means the attenuation value (D1 to D6) is for left channel exclusively; and if “L” and “R” all are “1” means attenuation value is for the both channel. LOUDNESS SETUP CODE The “LD” bit In the DATA code is for the Loudness function. When the “LD” bit is 0, the Loudness function is turned off (LS1=Off, LS2=ON) and the “LD” bit is 1 means the Loudness is turned ON (LS1=On, LS2=Off).
