<p>PURPOSE:To reduce the lead of a software in a write processing by connecting the D flip-flop of the output port of a CPU to one part of the address port for memory of a random access memory. CONSTITUTION:A D flip-flop 33 of an output port 3 is connected to one part of an address decoder 21 for memory of a random access memory 2. When a CPU 1 writes data to be transferred to the outside in the address of the address decoder 21 for memory shared by the D flip-flop 33 and the random access memory 2, write to the output port 3 and the random access memory 2 can be simultaneously executed. Thus, when the transfer of data to the outside and the processing of further using the data are frequently executed, the load of the software is reduced.</p> |
