I am using PGA2310 for programmable gain control. I also attach my C programme written for programming the gain through Atmega 8 controller.The problem here is that when I transmit 0xC0A5 as data to the IC then output waveform is displayed for very short duration of time and then the output is lost and shows zero. But if I transmit data 0xC0FF then the right channel and left channel correctly show the waveform

    I don't see anything attached.

    Did you verify your SPI signals with an oscilloscope?
