Figure 12. DIP-4 Calculation Boundaries
Note: EOP Abort packets sent out on the RX SPI4-2 may have the packet size modified. When an EOP
abort packet is received on the TX SPI4-2, the IXF1110 MAC sends the packet out to the SerDes
interface with an invalid CRC and is recorded in the TX statistics as a CRC error.

computed. A functional description of calculating the DIP-4 code is given as follows. Assume that
the stream of 16-bit data words are arranged as shown in
time moving downward). (The first word received is at the top of the figure; the last word is at the
bottom of the figure.) The parity bits are generated by summing diagonally (in the control word,
the space occupied by the DIP-4 code (bits a, b, c, d) is set to all 1s during encoding). The first 16-
bit result is split into two bytes, which are added to each other modulo-2 to produce an 8-bit result.
The 8-bit result is then divided into two 4-bit nibbles, which are added to each other modulo-2 to
produce the final DIP-4 code. The procedure described applies to either parity generation on the Rx
path or to check parity on the Tx path.
