OPERATION MODE MONITOR FOR MICROCOMPUTER |
摘要 |
An operation mode monitor for a microcomputer in which any one of a plurality of operation modes can be selected in response to an operation mode setting signal generated from an external circuit when reset. The monitor according to the present invention can check whether a predetermined correct operation mode has been selected in the microcomputer in accordance with a checking program and output an abnormal-operation-mode command signal in case of erroneous selection due to noise. In response to this signal, an alarm lamp is lit up; the microcomputer is automatically reset repeatedly until a correct operation mode is selected; and/or an actuator controlled by the microcomputer is automatically disabled. |
