The rate match FIFO inserts or deletes only one SKP symbol per SKP ordered set
received. Rate match FIFO insertion and deletion events are communicated to the
FPGA fabric on the pipestatus[2:0] port from each channel. The pipestatus[2:0]
signal is driven to 3'b001 for one clock cycle synchronous to the /K28.5/ COM symbol
of the SKP ordered set in which the /K28.0/ SKP symbol is inserted. The
pipestatus[2:0] signal is driven to 3'b010 for one clock cycle synchronous to the
/K28.5/ COM symbol of the SKP ordered set from which the /K28.0/ SKP symbol is
deleted.

SKP symbols are required to be deleted. Only one /K28.0/ SKP symbol is deleted per
SKP ordered set received.

symbols are required to be inserted. Only one /K28.0/ SKP symbol is inserted per
SKP ordered set received.
The rate match FIFO full and empty conditions are communicated to the FPGA fabric
on the pipestatus[2:0] port from each channel.
The rate match FIFO in PCIe mode automatically deletes the data byte that causes the
FIFO to go full and drives pipestatus[2:0] = 3'b101 synchronous to the subsequent
data byte.
