If you only want it to go to three, then you only need two flops as adding one to a 2-bit wide three overflows and becomes zero. If yo want to go up to four, then you want a synchronous reset. As sharvil pointed out, reset is is an input to bit ...

WebThe configuration bit 0 enables or disables the incrementing counter. When enabled, the counter will increment up to the value stored in the Load register. Once reached, it resets to 0 and starts counting again. The Value registers contains the current value of the counter. WebAsynchronous counters count the number of events solely using an event signal. Synchronous counters, on the other hand, use a common clock signal so that when several flip-flops must change state, the state changes occur simultaneously. A binary counter is a simple counter which counts values up when an enable signal is asserted and will
