Help with setint/interupt

[Digisapien]

Well when I was having.the problem with a switch not reacting fast enough ive dicovered the interupt command sequence and was wondering if somoene could give me a simple example using it. Say
With 20m2 chip a button and one led. I would appreciate it.as the syntax example would help. Confused on the way I designate the 8 bit to pin %00000000,%00000001

Hi,

Interrupts are only available on (up to) the 8 input pins of one port.

The "bit mask" concept may not be easy, but unless you tell us exactly which pin(s) you are using, and whether the signals are active high or active low, then we can't tell you what's needed (or whether it can work).

Cheers, Alan.

On a 20m2 only pins c.0 to c.5 can be used.
Pin c.0 is %00000001
Pin c.1 is %00000010
its all in the manual plus the editor will let you know if you try to use something else.
