Good day everybody!

I'm building the digital up/down counter using CD4510 as the counter with CD4511 as the display driver (7 segment). My problem is, I only needs the counter to count from 6 to 0. In short I would like to shorten the count from 9 to 6. Can anybody give me an idea on how to shorten the counting of CD4510? I REALLY APPRECIATE ANY HELP THAT YOU MAY EXTEND TO ME.
THANK YOU VERY MUCH IN ADVANCE.

Remove a bit

I dont know which circuit you are using so this may not work. Disconnect bit 4 (the one representing an 8) from your display driver and connect this to the reset of your BCD. That should work.

Hello!

Thank you very much PROF. INSANE for your suggestion and I will try your suggestion. But for your reference and may be you can give me more accurate suggestion regarding my problem, I got the circuit from BOWDEN'S HOBBY CIRCUIT. The title of the circuit is "9 SECOND DIGITAL READOUT COUNT DOWN TIMER". The website is
HTTP://OURWORLD.COMPUSERVE.COM

I'll wait for your response again.

Thank you and more power.
