Functionally equivalent to the txdeemph signal
defined in the PCIe specification revision 2.0.
Available only in PCIe Gen2 configuration.
1’b0: -6 dB de-emphasis
1’b1:-3.5 dB de-emphasis
Functionally equivalent to the rxpolarity
signal defined in the PCIe specification revision
2.0.
Available only in PCIe mode.
When asserted high—the polarity of every bit of
the 10-bit input data to the 8B/10B decoder gets
inverted.
