Hi
Now we have a TLK10031 connecting to a 10BASE-R SFP device
We test the Deep Remote Loopback mode and find the status PMA/PCS receive link up；but PMA/PCS fault condition is detected on tx path , so our connecting point （10BASE-R SFP point host computer）link down. The Flowing is our configuration and status register .How we debug the issue？ Thanks
