Hi BobbyFirminios,

 

 

I scrolled downwards and upwards but I can't find the screenshot that you mentioned.

 

Up/Down Counters can have separate upcounting and downcounting clocks or single clock with count direction input. The count direction pin can be named like UP/~DN, DN/~UP,  U/~D, D/~U, etc. The direction of counting can be reversed by inversion of logic state applied to the direction input pin.

 

 

Best regards,

G. Goodwin
