/* Tests on real CPC (by DanyPPC) */
So 2A is really during 5 NOPs... perhaps MEM_rd has to be slow down with one WAIT_n like for MEM_wr. Perhaps in this case 5T's instruction has not to be slow down. I have to fork r005.8.16c3 to test that.
About testbench border effects, I think that IO_ACKed instructions has to be under same rules (MEM_wr, modulo 4 etc)- update : same result in testbench using this way.
