Hi all,

I would like to get some advice from everyone on how best to tackle
this basic problem. My assembly codes
are segregated into different possible states of the system that i
build. I think it can be considered a Moore state machine.

Now, of the many states, there is one state that every states goes to
when the condition is right. Let say the condition is a Emergency
switch. Once inside the state, some algorithm is executed and when
the switch is flip back, the control will jump to only a particular
state, let's call it A state.

So my question is, what is the best way to implement this? Hardware
interrupt, Software interrupt or just plain old polling method?

Thanks.

Rgds,
Pang
