State Transitions
The CDP1805A and CDP1806A state transitions are shown
in Figure 13. Each machine cycle requires the same period
of time, 8 clock pulses, except the initialization cycle (INlT)
which requires 9 clock pulses. Reset is asynchronous and
can be forced at any time.

NOTE:
9. Pause (in clock waveform) while represented here as one clock
cycle in duration, could be infinitely long.
