Hi all,

Just wondering if anyone can clear something up for me.
I'm using the Vectored Interrupt Controller as decribed below, just wondering what function delaration extention I should use and what the difference is?

Thanks,
Andy

// Vectored Interrupt - Using Timer 0
VICVectAddr0 = (tDWord)Interrupt_Function;
VICVectCntl0 = 0x20 | 4;
VICIntEnable |= 1<<4;

void Interrupt_Function (void) __attribute__((interrupt));
void Interrupt_Function (void) __attribute__((interrupt ("IRQ")));
void Interrupt_Function (void) __attribute__((interrupt ("FIQ")));
void Interrupt_Function (void) __irq;
