FSM 3 (asynchronous reset)
15%fsmNow build the complete sequential version of the four-state Moore machine, including the state flip-flops:
| Current state | next state when in = 0 | next state when in = 1 | output out |
|---|---|---|---|
| A | A | B | 0 |
| B | C | B | 0 |
| C | A | D | 0 |
| D | C | B | 1 |
The active-high areset input is asynchronous and resets the machine into state A. out = 1 only in state D.
