Hi, Has anybody implemented nesting of interrupts in LH79520? I have a requirement where I need to switch to a higher priority interrupt when the controller is already processing in a lower prioroty ISR. Thanks for the help. Regards, Srikanth

Hi, The linux kernel does it, sort of. What exactly are you having problems with? If you're starting from scratch take a look at the ARM users manual, the ARM architecture has a number of exception modes that help with doing this sort of thing. Best Regards mt
