rective action. Thus, the Link Detection Packet ensure
strict compliance to the Microsoft PC97, PC98, and
Home PNA requirements.
The integrated Am79C978 controller supports auto-
configuration in the PCI configuration space. Additional
integrated controller configuration parameters, includ-
ing the unique IEEE physical address, can be read
from an external non-volatile memory (EEPROM) im-
mediately following system reset.
While consuming minimal network resources, AMD’s
innovative any1Home™ Link Detection Packet for
HomePNA networks provides a means to indicate to
the MAC and thus the upper layers of the system pro-
tocol that a valid network (as defined by Home Net-
working Alliance) has been detected. The Link
Detection Packet is also capable of detecting a network
failure and allows the upper layer protocol to take cor-
In addition, the Am79C978 controller provides pro-
grammable on-chip LED drivers for transmit, receive,
collision, link integrity, Magic Packet status, speed, ac-
tivity, power output, address match, full-duplex, or 100
Mbps status.
