Chapter 5 Operating Modes Overview
ICS1893AF, Rev D 10/26/04
The ICS1893AF operating modes are typically controlled from software.
The ICS1893AF register bits are accessible through a standard MII (Media Independent Interface) Serial
Management Port.
The ICS1893AF is configured to support the MAC Interface as a 10M MII or a 100M MII. The protocol on
the Medium Dependent Interface (MDI) can be configured to support either 10M or 100M operations in
either half-duplex or full-duplex modes.
The ICS1893AF is fully compliant with the ISO/IEC 8802-3 standard, as it pertains to both 10Base-T and
100Base-TX operations. The feature-rich ICS1893AF allows easy migration from 10-Mbps to 100-Mbps
operations as well as from systems that require support of both 10M and 100M links.
