HELP!!! Personality Modules for Microprocessors

HELP!! What the hell is a personality module for a microprocessor?? I mean I didnt know microprocessors had personalities.. HAHA funny huh.. lol.. anywhos I was wonderind exactly what a personality module for a microprocessor was and what its purpose was. I have searched the net for personality modules for a microprocessor but got only sites telling me that this product could take them or this product came with 3 personality modules but no actual information on what a personality module was, so if anyone could help me here it would be fantastic.
