Responding to: ???'s previous message
So, the trick is, to write the whole monitor as an ISR (quite naturally the serial ISR as the UART is usually given up for the monitor's communication), and keep the interrupt flag set when doing reti. That makes the single step, and trace is only a repetition of these.
EVERYTHING will be thrown off timewise, and basically ANY bug that does not have a timing component is a breeze to find.

the whole concept of an ICE is that the processor run true (till stopped)
