Description
Non-DQS capture mode clock.
Asserted w hen the training of the core
is complete.
The core is nonfunctional.
Asserted w hen the training reaches
the maximum number of iterations but
fails to adjust the pointers.
The core is nonfunctional. The
training must find a positive edge on
the bit 0 of data. The core did not find
this edge.
