Memory Write Cycle

The Memory Write Cycle takes one clock period.

All necessary signals are put in the buses at the begining of the clock period. These signals are: Address in the A-BUS, data in the D-BUS, M and M_WR.

Half clock later (42 ns), signals M and M_WR are pulled up. This makes effective the write operation into the memory chips.

At the end of the clock period, all signals are released.
