4.5 Device ID and Revision ID

The memory location 8006h is where the Device ID and

Revision ID are stored. The upper nine bits hold the

Device ID. The lower five bits hold the Revision ID. See

Section 11.5 “User ID, Device ID and Configuration

Word Access” for more information on accessing

these memory locations.

Development tools, such as device programmers and

debuggers, may be used to read the Device ID and

Revision ID.
