I am seeking information on how to turn the 68020's Instr cache off
and on via hardware.  The only literature I have been able to find says
that there is a cache disable pin, but not how to use it.  Does anyone
know exactly how this pin is used or where to find specs??  I have been told
that the MC68020 user's manual does not have this info. (hard to believe...)
     
Thanks for ANY help!!
