thanks scalerobotics and acetronics...I guess I had answer my own question

"...Can I use Timer0 as another prescaler to Timer1?...

I guess I could use Timer0 and at overflow set any available pin high then low (generate a pulse) and use it as input (via hardwire) to another timer which would be set to read an external clock (that would be the pulse).

Thinking out of the box.....

thanks again
