General description
The IP100 is a single-chip, full duplex, 10/100Mbps
Ethernet MAC + PHY incorporating a 32-bit PCI with
bus master support. The IP100 is designed for use in a
variety of applications including workstation NICs, PC
motherboards, and other systems utilizing a PCI bus
that require network connectivity to an Ethernet or Fast
Ethernet LAN.

The IP100 implements a rich set of control and status
registers. Accessible via the PCI interface, these
registers provide a host system visibility into the
features and operating state of the IP100. Network
management statistics are also recorded, and host
access to registers of the PHY device are facilitated
through the IP100’s PCI interface.

Transmit polling
The IP100 supports features for use in “Green PCs” or
systems where control over system power
consumption is desired. The IP100 supports several
power down states, and the ability to issue a system
“wake event” via reception of unique, user defined
Ethernet frames. In addition, the IP100 can assert a
wake event in response to changes in the Ethernet link
status.
