PURPOSE: To save memory, reduce the program forming time, and to simplify the system and to make low in cost, by writing in the content corresponding to the content latched at the output section in the same timing to latch the output section to the monitor RAM at the same time. CONSTITUTION: The circuit constitution is made that the output section OUT 2 is accessed as the write-in address from CPU 1 and the same content is written in the monitor RAM 4 at the same time. When the monitor RAM 4 is accessed as the read -in address to CPU 1, desired monitor can be made. In such a system, no program to write in the monitor RAM 4 is required and complcated and expensive hardware is not required. COPYRIGHT: (C)1979,JPO&Japio
