ADS7953 Converted data is shifted behind by two frames

Other Parts Discussed in Thread: ADS7953

Hi,

During ADS7953 analog to Digital conversion  , the converted channel output is delivered by two frames behind rather in the next frame.

The chosen mode is manual mode and SPI configuration. The channels are read from 0 to 16 in the ascending order. According to the data sheet  given, the Output of channel which is configured in the current frame will be clocked out in the next frame.

 

But in my case , the channel which is configured in the 1st frame is clocked out from 3rd frame. , the channel which is configured in the 2nd frame is clocked out from 4th frame and and so on.

 

Please can anyone help?

 

For the reference , the timing diagram is attached.

 

Regards

Raja
