Abstract
PURPOSE: To make it possible to display only the normal operation that CPU executes a program normally, by displaying only the operation state by using the respose signal of CPU to external signals arriving at constant intervals.
CONSTITUTION: In the constitution of analyzer 1, timer 2, memory 3, and CPU4, CPU4 controls analyzer 1 by the program stored in memory 3 to perform data processing. In this case, timer 2 is generally equipped to the processing system and timer 2 sends an interruption signal to CPU4 at constant intervals. After outputting a reset signal for this interruption signal to timer 2, CPU4 controls analyzer 1 according to the program. Since this interruption reset signal is not outputted unless CPU4 is in normal operation, using this signal provides the desired normal operation display.
