Abstract: A detailed execution schedule of self-diagnosis processing is set according to various requests. A self-diagnosis device includes a plurality of functional blocks, a storage unit that stores a plurality of processing units, each of which is an aggregate of some functional blocks selected from the plurality of functional blocks, and a start condition of self-diagnosis processing of each processing unit, and a self-diagnosis unit that selects the processing unit where the self-diagnosis processing is started based on the start condition of each processing unit and executes the self-diagnosis processing of each functional block in the selected processing unit.

Abstract: A semiconductor device includes a plurality of functional blocks, and a self-diagnosis circuit that controls a test for the functional blocks. When an interruption request is issued, the self-diagnosis circuit executes a test for one of the functional blocks.

Abstract: A microcomputer includes a first comparator which compares a voltage to be monitored, with a first reference voltage, a second comparator which compares the voltage to be compared, with a second reference voltage, and an interrupt control circuit which monitors the voltage to be monitored by the first and second comparators in parallel and, when a preset condition is satisfied, generates an interrupt signal.
