DESCRIPTION

Restart Auto-Negotiation

0, RW/SC

Restart Auto-Negotiation:

1 = Restart Auto-Negotiation. Re-initiates the Auto-Negotiation process.

If Auto-Negotiation is disabled (bit 12 = 0), this bit is ignored. This bit is

self-clearing and will return a value of 1 until Auto-Negotiation is initiated,

whereupon it will self-clear. Operation of the Auto-Negotiation process is

not affected by the management entity clearing this bit.

0 = Normal operation.

Duplex Mode

Strap, RW

Duplex Mode:

When auto-negotiation is disabled writing to this bit allows the port

Duplex capability to be selected.

1 = Full Duplex operation.

0 = Half Duplex operation.

Collision Test

0, RW

Collision Test:

1 = Collision test enabled.

0 = Normal operation.

When set, this bit will cause the COL signal to be asserted in response

to the assertion of TX_EN within 512-bit times. The COL signal will be

de-asserted within 4-bit times in response to the de-assertion of TX_EN.
