One thing I discovered on 8080 was that 0FFFFH is "infinity". Meaning it is better to produce this infinity than zero-division error, when system is oscillating

One thing I discovered on 8080 was that 0FFFFH is "infinity". Meaning it is better to produce this infinity than zero-division error, when system is oscillating around zero. Otherwise you have to insert zero-tests everywhere and waste precious clock cycles.
