Chapter 4 Operating Modes Overview
ICS1893CK-40, Rev. C, 06/02/09
The ICS1893CK-40 operating modes are typically controlled from software.
The ICS1893CK-40 register bits are accessible through a standard MII (Media Independent Interface)
Serial Management Port.
The ICS1893CK-40 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 ICS1893CK-40 is fully compliant with the ISO/IEC 8802-3 standard, as it pertains to both 10Base-T
and 100Base-TX operations. The feature-rich ICS1893CK-40 allows easy migration from 10-Mbps to
100-Mbps operations as well as from systems that require support of both 10M and 100M links.
