Joachim Wuerker Thanks for helping me with this. Here's me trying to set the MUX[1:0] to 01b. Verified my write to make sure it is 0x01. See the response frame on the right. Here's what I read on the ADC. Again the same result of 0x8000. Here's me sending the Standby and Wakeup commands before writing the Ch0 config register. But I did this for every register write as well: Verified that the channel config register is set correctly: Even with this the result of the ADC is 0x8000. Same scopeshot as before. Yes, I have verified the register settings after each write. Thanks in advance. Regards, Dheeraj
