I'm working on a project that is going to use a DESerializer DS90UB948 so in order to test it, I'm using an evaluation boards for both SER & DES and the Analog Launch Pad in order to get time advance. What I'm trying to configure is the I2C communication between them where the HOST controller is going to be connected as i2C master to the SER and our display as i2c slave (with address 0x12) to the DES using backchannel. My understand is that to communicate master and slave controllers, there must be configured as passthrough feature but not clear how to configure correctly. I think that I'm facing problems with the address of the slave cause I was able to see the i2c data only when configure the 0x17 register as PASS_ALL which is not correct at all. Could you explain with details how must be configure correctly? which register I should modify, with what values for both SER and DES (if required). Thanks in advance for your support.
