Problem Definition
Design a Modulo three counter. The count sequence is:
00 ? 01 ? 10 ? 00 ? 01 ? 10, etc.
There is an en input that should control counting (count when en=1, hold value when en=0). Assume ACLR line used to reset counter to 00.
How many states do we need? Well, we have three unique output values, so lets go with three states.
