Ordering, PVR, and JTAG Information
This section provides the part number nomenclature. For availability, contact your local IBM sales office.
The part number contains a part modifier. Included in the modifier is a revision code. This refers to the die
mask revision number and is specified in the part numbering scheme for identification purposes only.
The PVR (Processor Version Register) and the JTAG ID register are software accessible (read-only) and
contain information that uniquely identifies the part. Refer to the
PowerPC 405EP Embedded Processor
User's Manual for details on accessing these registers.
