User-defined packet ID. Only valid with rxrdp_sop .
Enable signal on the Atlantic interface. Indicates that
the data is valid.
Indicates that the input FIFO buffer is not full.
Start of packet indicator on the Atlantic interface.

Number of empty bytes in the data word.
User data bits.
User-defined packet ID.
rxhpp_ena
Input
rxhpp_clk
Enable signal on the Atlantic interface. Indicates that
the data is to be read on the next clock cycle.
Input (No FIFO buffer) determines whether flow
control is required on this port.When this signal is
rxhpp_dav
Input
rxhpp_clk
low, the fill level has been breached. When this signal
is high, the FIFO buffer has enough space for more
words.
Output (With FIFO buffer) represents the buffer’s fill
rxhpp_dav
Output

level. This signal is high when the level is above FTL
or if an EOP is in the buffer.
