Okay this is the code that I'm trying:


void CapturePin() __attribute__ ((interrupt));
void CapturePin()
{
	unsigned long temp = T0CR2;
	SerialSendString("Hi");
	T0IR = 1;
	VICVectAddr = 0;
}

void InitCapture()
{
	VICVectAddr0 = (unsigned)CapturePin;
	VICVectCntl0 = 0x20 | 4;
	VICIntEnable = 0x00000010;

	PINSEL1 = 0x00000002;
	T0PR = 0x00000000;

	T0CCR = 0x000001C0;
  	T0TCR = 1;
	SerialSendString("Capture pin initialised\n");
}

When I turn on my signal generator, nothing happens even though I 
expect it to display "hi" on my terminal.
It works fine if I set the PINSEL to EINT0, instead of CAP.. what 
could be going on here?

thanks
