As an example microcode can be used to disable certain circuits. Imagine something like a loop buffer, a structure that captures decoded instructions and re-executes them in a loop bypassing instruction fetches. If it turns out to be buggy a microcode update might disable it entirely, effectively sacrificing an optimization for stability. 17/31
