DS90UB949A-Q1EVM: Back channel data

Hello experts,

I have a question about how to get access to the back channel data.
For example, accessing one of the deserializer's register in a SER/DES combination.
There is a function in the built-in Python in ALP (ReadI2C) but I want to understand how does it work from a register point of view.

Hi Mohamed,

To clarify, are you trying to read a deserializer's register from the serializer? If so, you need to use the device address to access it from the serializer.
