with external feedback, see Figure 5
This configuration is a typical state-machine design with feedback signals sent off-chip. This external feedback
could go back to the device inputs or to a second device in a multi-chip state machine. The slowest path defining
the period is the sum of the clock-to-output time and the input setup time for the external signals
