ICS1893AG Data Sheet - Preliminary
Chapter 5 Operating Modes Overview
Chapter 5 Operating Modes Overview
The ICS1893AG operating modes are typically controlled from software.
The ICS1893AG register bits are accessible through a standard MII (Media Independent Interface) Serial
Management Port.
The ICS1893AG 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 ICS1893AG is fully compliant with the ISO/IEC 8802-3 standard, as it pertains to both 10Base-T and
100Base-TX operations. The feature-rich ICS1893AG allows easy migration from 10-Mbps to 100-Mbps
operations as well as from systems that require support of both 10M and 100M links.
This chapter is an overview of the following ICS1893AG modes of operation:
• Section 5.1, “Reset Operations”
• Section 5.2, “Power-Down Operations”
• Section 5.3, “Automatic Power-Saving Operations”
• Section 5.4, “Auto-Negotiation Operations”
• Section 5.5, “100Base-TX Operations”
• Section 5.6, “10Base-T Operations”
• Section 5.7, “Half-Duplex and Full-Duplex Operations”
