RESERVED
AUTO-NEGOTIATION FAIL:
completes and no common technology was found. It remains set until
read.
DUPLEX: If set it indicates full-duplex operation. If clear it indicates
half-duplex mode.
RATE: Always clear indicating 10BASE-T mode.
RECEIVE PASS: In 10BASE-T mode, this bit indicates that Manchester
data has been detected.
RECEIVE LOCK: Indicates that the receive PLL has locked onto the
received signal for the selected speed of operation (10BASE-T). This
bit is cleared whenever a cycle-slip occurs, and will remain cleared until
it is read.
RESERVED. Must be zero.
DESCRIPTION
Receive Error Interrupt: This bit is reserved for 100Base-TX
Page Received Interrupt: This bit is set when a new page has been
received from the link partner during auto-negotiation.
Parallel Detect Fault Interrupt: This bit is set by the auto-negotiation
logic when a parallel detect fault condition is indicated.
Link Partner Acknowledge Interrupt: This bit is set by the auto-
negotiation logic when FLP bursts are received with the acknowledge
bit set.
Link Status Change Interrupt: This bit is set when the link transitions
from an OK status to a fail status or vice versa.
Remote Fault Interrupt: This bit is set when a remote fault condition
has been indicated by the link partner.
Auto-Negotiation Complete Interrupt:
negotiation logic upon successful completion of auto-negotiation.
