tried to use the cache. apparently I had already removed a connection from a23_fetch so it wasnt there but fetch logic was hoping to find it. tried to get it to work with verilator, decided to just chuck it completely. so if you enable it it doesnt do anything you keep on running without crashing

adding systick example. Remembered to fix a problem in vmain, when you run forever the tick variable rolls over and you have a short period between the rollover and tick < 11 where it doesnt watch the bus. Changed the logic there so that doesnt happen
