Hi all,
has anyone tried to successfully connect the motorola 68hc11 to the zilog z85230? I am trying to make them work together but it seems I am able to read but not to write.
data from 68hc11 are directly connected to the data lines on the z85230. Control signals rd and wr come from 68hc11. chip enable and d/c come from a PLD.
I am thinking about delaying the write signal, in order to make it fit the z85230 timing constraints: could this help?
Thanks in advance for your time and considerations. Giovanni
