RE: PCS Management Counters



Title: RE: PCS Management Counters

Ben,
Thanks for your reply.

Where will these counters be used?
I mean do these counters give some kind of
count which tells the number of packets that
will be thrown away by the MAC because of
"ERROR" column?

If the counter gives the number of ERROR columns
inserted by PHY how can somebody use
it for statistics?

Vivek,

Since, according to the state machine conventions and figure 49-14,
the state is actually re-entered on every clock edge, the counter
would be incremented twice (in your case) or once for every clock
cycle spent in that state (in general).
