<p>PURPOSE:To obtain a microcomputer with a high reliability by which the runaway of a program can be detected, at the time of executing the program. CONSTITUTION:Discontinuous command display data 7 indicating whether each command constituting the program is a continuous command or a discontinuous command, are stored on a ROM 1 by making the data correspond to each command one by one. Then, at the time of executing the program, the execution of the discontinuous command is set at a discontinuous command execution flip flop 3, and this set value is compared with the discontinuous command display data by a comparator 4, and when they are unmatched a runaway detection signal 105 is outputted by the comparator 4.</p> |
