== Instruction Cycle ==
Just like the Z80, the 8080 is composed of M-cycles and T-states.
Each ctock period marks a state; 3 to 5 states constitute a machine cycle; and 1 to 5 machine cycles comprise an instruction cycle.
A full instruction cycle requires anywhere from 4 to 18 states for its completion, depending on the kind of instruction involved.
