IXF1104 4-Port Gigabit Ethernet Media Access Controller
Enable packet padding and CRC appending on transmitted packets in bits 6 and 7, as
needed.
Set bit 5 to 0x0.
b. Fiber Mode:
Write the reserved bits to the default value.
Enable Packet padding and CRC Appending on transmitted packets in bits 6 and 7, as
needed.
Set bit 5 to 1 to enable auto-negotiation.
Set bit 5 to 0 to enable forced mode operation.
13. Assert (set to 1)
14. Wait 1 to 2 μs.
15. Perform additional device configurations, as needed.

Disable and Enable Port Sequences
Intel recommends the following sequences to disable and enable individual ports, and for dropped
links. When a link is dropped, Intel recommends the port be completely reset and flushed to
remove packet fragments that may interfere with the auto-negotiation process on link recovery.
6.2.1
Disable Port Sequence
Use the following sequence to disable an individual port:
1. Disable the port using MAC port enable/disable bits
2. Apply TX FIFO soft reset
3. Introduce some delay to allow completion of packet transmission (not necessary if link is
dropped).
4. Flush TX
5. Apply MAC soft reset
6. Apply RX FIFO soft reset
6.2.2
Enable Port Sequence
Use the following sequence to enable an individual port:
1. Enable the port(s) using MAC port enable/disable bits
2. Disable TX FIFO soft reset
3. Reset flush TX
4. Disable MAC soft reset
5. Disable RX FIFO soft reset
