Hello,

    CCS makes a lot of overhead when using an interupt, like:

        #INT_RTCC
        void interrupt(void)
        {
            // put your routine here
        }

    But you can use the #INT_GLOBAL that doesn't make all that overhead. It
only cares about the RETFIE instruction.

    Now, how can I do the context saving in CCS using minimal assembly
commands?

        #INT_GLOBAL
        void interrupt(void)
        {
            // saving W, STATUS, do_i_need_to_save_anything_else?
            // put your routine here
            // restoring W, STATUS, do_i_need_to_restore_anything_else?
        }

    Thanks,

    Brusque
