I'm using an ADS8634 4-Channel 12-Bit ADC with a SPI bus. According to the data sheet, page 32, the first 4-bits in the 16-bit response, when reading converted data, are the address of the channel the next 12-bits belong too. And yet, if you look at my scope's screen shot, you will see that the address is 6. That doesn't seem possible on a 4-channel device. Is there something wrong with the SPI bus configuration (I've tried all 4 SPI bus modes) or with the device itself?
Yellow = Chip select
Blue = SPI Clock
Purple = data
