I'm having trouble installing the EINT0 interrupt.  I can install the 
Timer0 interrupt no problem:

  T0TCR = 1;                                  // Timer0 Enable
  VICVectAddr0 = (unsigned long)MyISR;        // set interrupt vector 
in 0
  VICVectCntl0 = 0x20 | 4;                    // use it for Timer 0 
Interrupt
  VICIntEnable = 0x00000010;                  // Enable Timer0 
Interrupt

If I run this code & examine VICIRQStatus I get 0x00000010 as 
expected.

But if I try to install EINT0 in the same place (VICVect0):

  VICVectAddr0 = (unsigned long)MyISR;        // set interrupt vector 
in 0
  VICVectCntl0 = 0x20 | 15;                   // use it for EINT0 
Interrupt
  VICIntEnable = 0x00008000;                  // Enable EINT0 
Interrupt

and check VICIRQStatus I get 0x00000000 (nothing...)

What am I doing wrong?  I tried setting EXTINT = 1 but this doesn't 
seem to do any good.

Thanks,
