Hi Darrel,

Start:
      If Capture = 0 then ' ignores 1st capture
         Goto Start
      endif

      T1CON.0=1
      Capture = 0 
      
CaptureLoop:
If Capture = 0 then 
  Goto CaptureLoop
endif
T1Con.0=0  
period.LowByte=CCPR1L
period.HighByte=CCPR1H

With both PICs running at 20MHz, CCPR1L & CCPR1H should have the same values - since
it's all done in hardware with the capture module capturing the value of timer1 after the
4 rising edges.

And the value being captured is before the multiply.
