Subject: run_avr: Add a way to trace just interruots vectors
X-Git-Tag: v1.0a3~10
X-Git-Url: https://git.htl-mechatronik.at/public/?a=commitdiff_plain;h=46876e7b76884fb5134386c0462601644c847927;p=sx%2Fsimavr.git

run_avr: Add a way to trace just interruots vectors

Calling run_avr with -ti <value> will trace the scheduling
of that pacticular vector.
You can have up to 8 traces.
