PIPE rxstatus 1
detected and reported on a per lane basis. For example:
●

●
●
●
Not meaningful when using the generic PIPE PHY interface.
PIPE polarity inversion 1
LTSSM requires the PCS subblock to invert the polarity of the
received 10-bit data during training. Not meaningful when using
the generic PIPE PHY interface.
Elastic buffer counter 2. This signal reports the number of
symbols in the elastic buffer.
Monitoring the elastic buffer counter of each lane can highlight
the PPM between the receive clock and transmit clock as well
as the skew between lanes. Not meaningful when using the
generic PIPE PHY interface.
