#100784 - Rampant code execution
Responding to: Andy Neil's previous message
Rupesh Deenadayalan said:
i am working in a project where a 16 bit AMD188 microcontroller is ...
my doubt is when the microcontroller reaches to fffffth memory location it rolls over to 00000th memory location

If your code gets into that situation it is seriously broken!

If I remember correctly, The x86 architecture has its interrupt vector table at address zero in memory (the first 1K?) - so if you start executing that, you're in BIG TROUBLE!!
(Also remember that the x86 interrupt vector table contains only addresses - not executable code...!)
