How can I set a starter number of 4-bit binary ripple counter
I can create a 4-bit ripple counter (That can count 0000-1111 (0-15)) by JK flip-flop
but I can't set a starter number of it.
By default, when reset is 1. the counter print 0000
and I change reset switch to 0, the counter count up from 0000 to 1111 and then change to 0000 and count up again.
1. If I WANT to set a starter to 1010 and then count from 1010 to 1111 then change to 0000 and STOP. How can I do it?
2. If I WANT to set a starter to 1010 and then count from 1010 to 1111 then change to 0000 and CONTINUE running from 0000-1111 and loop again and again. How can I do it?
Can you show me the FULL circuit with pin name on each device & description?
Assume that, I use LogicWorks and simulate the circuit.
Thank you very much.
