8. Module: Product Identification System
The “PIC18F2221/2321/4221/4321 Product Identi-
fication System” illustration, on Page 393, is
changed to correct the following inaccuracies:
• Tape and reel delivery is available for TQFP,
• The part number code for QFN packages is
The illustration is changed, as shown, with bold
text indicating the corrected information.
