/* RET cc and WAIT_n timing analysis */
"Simples!" - ralferoo
(4T equals us => modulo 4 synchronization of M1)
So you slow down instructions following a slowing down instruction table, slowing it the less you can, and then IO_ACK comes or not, and then you synchronize next M1 putting WAIT_n during T2 modulo 4. IO_ACK two autowaits are not prolongated.
