DescriptionPort Link-layer Status 1.

Indicates the status of the Link Layer for either Port 0 or Port 1. The Port monitored is controlled by the value programmed into the Port Config Register. This register acts as an accumulator for the SERDES errors. Each counter can be cleared by writing 8hFF to the individual byte. Note: All Status Registers have no predefined Reset value. The value shown in reset is a typical value that will be read after reset but will be dependent on the SERDES status, the actual value read can differ from this.
