I'm still trying to install my own timer, and stumbled over the
'fact', that the system's timer ('C') is said to generate a 200hz-
interrupt... 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.
