PROBLEM TO BE SOLVED: To prevent wrong data from being read and shorten an ineffective time when the function of a circuit is stopped by generating a level-given reset signal immediately according to the contents of trouble when the trouble occurs, and resetting and restarting the circuit. SOLUTION: An OR circuit 52 allows a reset signal generating circuit 53 generating a reset signal to generate a reset signal if one of interruption signals IRQ1-IRQ3 is generated. When one of the IRQs1-3 is generated, the reset signal generating circuit 53 outputs the reset signal. A combinational circuit 56 which performs a selecting process under prescirbed conditions for the reset signal is a set/reset circuit and performs resetting operation for a recovery after a set and a reset signal for secure operation even in case of instantaneous generation of an interruption, thereby making the combinational circuit 56 securely operate. |
