Allright, sorry about that.It gets confusing when you tack a question onto an old thread, like this one - http://forum.allaboutcircuits.com/showthread.php?t=7185
We prefer that you not hijack threads, but start a new one.
You can either shift to an all 0 state, or use the parallel load function to set to all 0's.
The Functional Description in the datasheet tells how to do it.Allright, sorry about that.
Actually it can be cleared with more than one clock pulses with shift operation but I couldn't figure out how to do it with one clock pulse. How can we use parallel load to do this?
