Instant Interrupts - Revisited

[Bruce]

The major issue you have with the Diolan loader is that it has Enhanced CPU mode
enabled. I.E. XINST = ON.

So code compiled with PBP simply is not compatible, and will not run on the PIC as
expected unless you disable Enhanced CPU mode.

Here's a simple example you can try. Make sure you set XINST = OFF, then run this;

MyVar VAR WORD
LED VAR PORTD.0 

Loops:
 FOR MyVar = 0 TO 100
   High LED        
   GOSUB BLINK  

   Low LED       
   GOSUB BLINK  
 NEXT MyVar
 
   Goto Loops 

BLINK:
    PAUSE 200
    RETURN
    
    End

Now run the exact same code, but set XINST = ON and give it a whirl.

Once you flip that switch to enable Enhanced CPU mode, ALL your code needs to be using
the extended instruction set. Try it with ACCESS EQU 1 as well. Still no go.
