I am having a strange problem - it seems something with the UART interrupt. Simple when returning from the UART interrupt vector in one specific moment it seems the PC is not set to the adress where the program was interrupted. As I said it seems because I can't realy verify it though using C (if you had any idea how to check this please tell me). Well, not in a simple way, but if you are persevere enough, look at the disassembly/asm... You can do one thing, though: check SP at the beginning of the highest priority interrupt (or, better at the beginning of ALL interrupts). You shall be able to check the depth of stack needed for execution of that particular ISR - you do keep them short and simple don't you... :-) JW |
