4.4.2. Test Pattern Checker
The test pattern checker detects exceptions and reports them to the control interface via a 32-element deep internal FIFO. Possible exceptions are data error, missing start-of-packet (SOP), missing end-of-packet (EOP), and signaled error.
As each exception occurs, an exception descriptor is pushed into the FIFO. If the same exception occurs more than once consecutively, only one exception descriptor is pushed into the FIFO. All exceptions are ignored when the FIFO is full. Exception descriptors are deleted from the FIFO after they are read by the control and status interface.
