Hi, I am trying to create a 60 second timer which counts to 60 and then resets to 00 and continues to count up. The design must be done with a 74LS163 for the ones digit and an asynchronous counter designed with J/K flip-flops for the tens digit. Both are connected to 74LS48 BCD to Seven Segment decoders.
Currently, I am capturing the 6 from the tens counter and the 1 from the ones counter and wiring this to both the clears of the J/K flip-flops and the clear of the 74LS163. This causes it to reset from 60 to 01. If I instead only capture the 6 from the tens counter, it will reset at 59 to 00.
How can I reset at 60 without displaying a 01 immediately after it resets?
