Note:

1. This feature requires Intel supplied software. To determine if this feature is enabled

by a particular software release, see the Intel® IXP400 Software Programmer’s

Guide.

2. Although this feature has direct access from the Intel XScale® Processor, this

feature monitors the activity of the MII interfaces which requires Intel-supplied

software to operate.

3. IEEE 1588 hardware assistance is not available for the Intel® IXP455 Network

Processor.
