AFE5832LP: Data transmit is not correct

Part Number: AFE5832LP


Dear Expert

I used the RAMP testing mode of AFE5832LP to verify the data of each pathway. The result shows the following phenomenon. May I ask if this is a normal phenomenon, or if your evaluation board is also in this form.
Abnormal phenomenon: Within the same AFE5832LP, the data of the first 16 channels is consistent, and the data of the last 16 channels is consistent. But the data of the 16 channels before and after are inconsistent, which feels a bit inconsistent with the theory

We will use the image above to illustrate:
1: The data of channels 1-16 are all the same and increasing, for example, channel 15 is 61B, 61D, and 61F
2: The data from channels 17 to 32 are all the same and increasing, such as A2B, A2D, and A2F for channels 17
In theory, the data from channels 1 to 32 should all have the same incremental value. For example, channel 17 should also have 61B, 61D, and 61F, which means that starting from channel 17, there is an overall increase in offset
Equivalent to saying, I need to confirm the following questions:
1: Is this phenomenon correct? Is it true that the chip itself is like this
2: If this phenomenon is not correct, then I need to check my design to see where the abnormality occurred
