I finally had some time to do some debugging on my unit. The 8212 seems to reset properly as all LED's goes out during the reset. But as soon as RST is released they light up again. The 8212 DS1* input has a 2MHz continuous clock and DS2 input is connected to the processor SYNC output and seem to be getting the proper signal also. As far as I can see these are the only inputs that would affect the clocking of the data so I am suspecting that the 8212 has gone kaput. I have ordered a new one so hopefully this will solve my problems.
