Deepan,

Reset device by writing 0[1]

Set the VCA control register to 0bxx000011 by writing 0x0003 to register 16. This should route Ch1 input to CW0.

Thanks,

Chuck Smyth

Thank you for your reply sir, I wrote that register as 0x0003 and i got the output, but its routing all eight input channels. That means it enables every input channels and gives output.
