But according to the POCI and SCLK waveform, the last 16 bits are the data I want to receive, send command to process RX data, this part is what I said to send 0x00000000 all the time[/quote] Yes, I also seen this. Since you send your command, then you need to read data from SPI FIFO. You will receive 2bytes after you send command, this part is region, useless, it's 0x0000. Then you need another two bytes to be received from SPI FIFO, this part is region 2, received data from ADS.
