3 Configuration
This section includes information on the various configuration options available with the TLK100. The
configuration options described below include:
• Auto-Negotiation
• Auto-MDIX
• PHY Address
• LED Interface
• Loopback Functionality
• BIST
• Cable Diagnostics
3.1 Auto-Negotiation
The TLK100 device can auto-negotiate to operate in 10BASE-T or 100BASE-TX. If Auto-Negotiation is
enabled, then the TLK100 device negotiates with the link partner to determine the speed and duplex with
which to operate. If the link partner is unable to Auto-Negotiate, the TLK100 device would go into the
parallel detect mode to determine the speed of the link partner. Under parallel detect mode, the duplex
mode is fixed at half-duplex.
The TLK100 supports four different Ethernet protocols (10 Mb/s Half Duplex, 10 Mb/s Full Duplex, 100
Mb/s Half Duplex, and 100 Mb/s Full Duplex), so the inclusion of Auto-Negotiation ensures that the
highest performance protocol will be selected based on the advertised ability of the Link Partner. The
Auto-Negotiation function within the TLK100 can be controlled either by internal register access or by the
use of the AN_EN, AN_1 and AN_0 pins.
The state of AN_EN, AN_0 and AN_1 pins determines whether the TLK100 is forced into a specific mode
or Auto-Negotiation will advertise a specific ability (or set of abilities) as given in Table 2-1. These pins
allow configuration options to be selected without requiring internal register access. The state of AN_EN,
AN_0 and AN_1, upon power-up/reset, determines the state of bits [8:5] of the ANAR register (0x04h).
