As far as I understand for these magic ports you need spare addresses (unused to be more precise) or you are "removing an IO component from the silicon". Currently I decided to remove PORT "E" which are the addresses 0x21, 0x22 and 0x23 using 0x21 instead of 0x20 prints the following out on the shell:

As a hint I would suggest to use a common define for the -R and the related C statement, otherwise ... - I think you know too well. But I'm confused about the debugger behavior. I'll check in the oldish checkdebug - style especially find a gdb-GUI :-) _______________________________________________ Simulavr-devel mailing list Simulavr-devel@nongnu.org http://lists.nongnu.org/mailman/listinfo/simulavr-devel
