2.3.10.2 100BASE-TX Link Integrity Algorithm (100 Mbits/s)
Because the IEEE 802.3 specification defines 100BASE-TX to have an
active idle signal, the device uses the squelch criteria and descrambler
synchronization algorithm on the input data to determine if the device
has successfully established a link with a remote device (called Link
Pass state). Refer to IEEE 802.3 for more details if needed.
2.3.10.3 AutoNegotiation Algorithm
As stated previously, the AutoNegotiation algorithm is used for two
purposes:
To establish a link to and from a remote device
To automatically configure the device for either 10 or 100 Mbits/s
operation and either Half- or Full-Duplex operation.
The AutoNegotiation algorithm is the same algorithm defined in IEEE
802.3 Clause 28. AutoNegotiation uses a burst of link pulses, called fast
link pulses (FLPs), to pass up to 16 bits of signaling data back and forth
between the device and a remote device. The transmit FLP pulses meet
