IXF1110 10-Port 1000 Mbps Ethernet Media Access Controller
The SPI4-2 specification details all available Payload Control Words and should be used to
reference the specific meaning of each. The IXF1110 MAC supports all required functions per this
specification. However, there are various specifics in the way certain Control Words affect the
balance of the IXF1110 MAC operation, such as how the device deals with EOP Aborts.
The SPI4-2 specification allows the EOP Abort Payload Control word, which signals that the data
associated with a particular frame is errored and should be dropped, or errored and dropped by the
far-end link partner. In the IXF1110 MAC, all TX SPI4-2 transfers that end with an EOP Abort
code have the TX SerDes CRC corrupted. This is true regardless of the MAC configuration.

may be active (sending data), paused (not sending data but pending the completion of an
outstanding packet), or inactive (not sending data, no outstanding packet).
EOP Abort
EOP Aborts is an End-of-Packet (EOP) termination that is sent out of the IXF1110
MAC SPI4-2 to tell the upstream SPI4-2 device that a packet is bad. EOP Abort packets are sent by
the IXF1110 MAC under the following conditions:
