Heder pins on the EZ USB development board

Question: Why are there header pins on the EZ-USB AN21xx development board and what purpose do they serve?

 

Answer:

The five headers P1-P5 serve three purposes.
1) They mate with the prototyping board supplied in the EZ-USB AN21xx Development Kit.
2) They allow direct connection of HP (Agilent) Logic Analyzer pods (Agilent P/N 01650-63203).
3) They allow general purpose probing by other logic analyzers or oscilloscopes.
