/* Instruction timing : talk about r005.8.16c20 */
Prefixed instruction has only one M1 ?
Is IO_ACK itself a separated instruction ?I think no, it's a hack of a current instruction, adding two autowait and making its business during this inserted times.
IO_ACK offset into INT (interrupt) should not implicated by WAIT_n generator, and it seems that a WAIT_n during T2 is ignored because of autowait already inserted at this moment... for synchronizing an IO_ACK, I have normaly to insert WAIT_n during T2+2.
