1. An apparatus comprising:
- a plurality of N-bit counters each coupled with a plurality of receivers coupled with corresponding serial data links;
a multiplexer coupled with the plurality of N-bit counters to select an output signal from one of the plurality of N-bit counters; and
an expanded counter coupled with the output of the multiplexer to count output signals from the multiplexer.

5. A system comprising:
-
a plurality of test registers; a port to communicate via a point-to-point serial link having a receiver and a control circuit coupled with the receiver, the control circuit having a plurality of N-bit counters each coupled with a serial data link, a multiplexer coupled with the plurality of N-bit counters to select an output signal from one of the plurality of N-bit counters, and an expanded counter coupled with the output of the multiplexer to count output signals from the multiplexer, the control circuit coupled with the plurality of test registers. - View Dependent Claims (6, 7, 8)

9. A method comprising:
-
counting bit errors detected in a plurality of data streams received via a plurality of point-to-point serial links using a plurality of corresponding N-bit counters; and selectively enabling a multiplexer to pass output signals from the plurality of N-bit counters to an expanded counter to expand counting capacity utilizing the extended counter to enable bit error counting beyond a capacity of the N-bit counters. - View Dependent Claims (10)
