    What does the Datasheet say?

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

    A complex system that works is invariably found to have evolved from a simple system that worked.A complex system designed from scratch never works and cannot be patched up to make it work.

    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,

    STOne-32.

    Well, thanks to everybody.

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