Hi,

The users manual says that the CRP may be set to disable ISP. 
Will these modes prevent booting from USB?

Seems like it should but the manual seems pretty specific in stating ISP is disabled with no mention of the other boot sources.

...or am I misunderstanding CRP1?  Does that prevent even application code from reading the flash memory?


Thanks,
Tony

P.S. What I am worried about is... can a small USB bootable program be run and then read the contents of the program memory?
So I hope I am missing something.  Must be...
