#use delay(clock=20000000)
#fuses HS,NOWDT,NOBROWNOUT,NOPUT,NOLVP,DEBUG,NOSTVREN,NOPROTECT

#int_TIMER2
void TIMER2_isr() {
   output_toggle(PIN_C1);
}

void main() {
   setup_timer_2(T2_DIV_BY_16,249,16);
   enable_interrupts(INT_TIMER2);
   enable_interrupts(GLOBAL);

setup_timer_2(T2_DIV_BY_16,255,16);

Should give an interrupt every 13.1ms (@20Mhz xtal clock)
