How it works
A value is placed in the inputs from 0 to 7 to define how much it counts. Then, the start input is set to 1 to load that value, and it begins to count. When it reaches zero, the end flag is raised.
How to test
External hardware
It is recommended to use switches for the inputs, a button for the start input, and LEDs for all the outputs.
