Chapter 4 Operating Modes Overview

The ICS1893CF operating modes are typically controlled from software.

The ICS1893CF register bits are accessible through a standard MII (Media Independent Interface) Serial

Management Port.

The ICS1893CF 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 ICS1893CF is fully compliant with the ISO/IEC 8802-3 standard, as it pertains to both 10Base-T and

100Base-TX operations. The feature-rich ICS1893CF 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 ICS1893CF modes of operation:

• Section 4.1, “Reset Operations”

• Section 4.2, “Power-Down Operations”

• Section 4.3, “Automatic Power-Saving Operations”

• Section 4.4, “Auto-Negotiation Operations”

• Section 4.5, “100Base-TX Operations”

• Section 4.6, “10Base-T Operations”

• Section 4.7, “Half-Duplex and Full-Duplex Operations”

• Section 4.8, “Auto-MDI/MDIX Crossover”
