Is there a way to disable interrupts at the VIC or does it have to be 
through the CPSR?  I tried something like this:

unsigned save;

save = VICIntEnable;
VICIntEnClr = 0xffffffff;

// interrupts disable here

VICIntEnable = save;

This method definitely does not work as expected.  Any ideas?

Thanks,

JT
