port 'C' is for LCD functionality... but by default it's not being
used... (unless you have an LCD) you'd have to issue something like:
(*(volatile unsigned char *))0xfffff413)=0xff; /* set all pins to no
(*(volatile unsigned char *))0xfffff400)=0xff; /* set all pins to output
and -ta-da you're program should work!
good luck ;)
