rxfreqlocked0
(1)
Input
When asserted indicates that the
pclk_in
used for PIPE
simulation is valid.
rxdataskip0
Output
For Gen3 operation. Allows the PCS to instruct the RX interface
to ignore the RX data interface for one clock cycle. The following
encodings are defined:
• 1’b0: RX data is invalid
• 1’b1: RX data is valid
