As far as I can see it's installing procedure uses a division factor of 64 (decimal, I suppose), and a counter that's set to 192 (C0 hex). IF I believe my documentation which says that the MFP 68901 uses a 4Mhz - clock cycle, then what? All the divisions mentioned above wouldn't at all generate a 200hz-interrupt. Am I wrong? What I need are the data and control values for getting a one-millisecond resolution. Any suggestions? Yours in advance, Klaus. -- Klaus Hahn --
