Intel® 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) “Port Enable ($0x500)”.

14.Wait 1 to 2 μs.

15.Perform additional device configurations, as needed.

6.2Disable 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.

6.2.1Disable Port Sequence

Use the following sequence to disable an individual port:

1.Disable the port using MAC port enable/disable bits [“Port Enable ($0x500)” Bits (3-0)].

2.Apply TX FIFO soft reset [“TX FIFO Port Reset ($0x620)” Bits(3-0)].

3.Introduce some delay to allow completion of packet transmission (not necessary if link is dropped).

4.Flush TX [“Flush TX ($ Port_Index + 0x11)” Bit 0].

5.Apply MAC soft reset [“MAC Soft Reset ($0x505)” Bits(3-0)].

6.Apply RX FIFO soft reset [“RX FIFO Port Reset ($0x59E)” Bits(3:0)].

6.2.2Enable Port Sequence

Use the following sequence to enable an individual port:

1.Enable the port(s) using MAC port enable/disable bits [“Port Enable ($0x500)” Bits (3-0)].

2.Disable TX FIFO soft reset [“TX FIFO Port Reset ($0x620)” Bits(3-0)].

3.Reset flush TX [“Flush TX ($ Port_Index + 0x11)” Bit 0].

4.Disable MAC soft reset [“MAC Soft Reset ($0x505)” Bits(3-0)].

5.Disable RX FIFO soft reset [“RX FIFO Port Reset ($0x59E)” Bits(3:0)].
