| Most preferable to see some schematics. The circuit use TOGGLE ENABLE input and if it’s connected to high level will stop counting.

Dear mister_rf
This I attach the counter schematic, from our discussing previously, I have few question to you, there are:
1. How to modifying the lowest number (on schematic) will be fixed number if I activated the stop button?
2. I made start/stop function from pulse generator output, is it true? If no, please your suggestion how to create the start/stop function?
I very appreciated for your problem solving,
With best regards,
Bharitta

Dear mister_rf,
thanks for your reply, i will try it. it's very useful.
my previously schematic, i build the start/stop function from pulse generator output, is it true? If no, please your suggestion how to create the start/stop function?
I very appreciated for your problem solving,
With best regards,
