What does the Datasheet say?

(I've certainly used PC1 for an external interrupt)

Well, thanks to everybody.

The guy was partly right. I really cannot use PA0 and PC0 together. Everything seemed so clear...

Hi,

You can have ''PA0'', ''PA1'', ''PC2'', ''PC3'', ''PA4'', ''PA5'' all enabled at a time, but not ''PC0'', ''PC1'' and inputs 0 and 1 are already assigned to Port A, but you can configure them later if all them are not used in same time.

Cheers,
