1. An electronic control unit comprising a microcomputer configured to be started by a plurality of starting factors, wherein
different operation modes are associated with each of the starting factors, and a resource is associated with each of the operation modes, and
the microcomputer is configured to identify a starting factor in an initialization process started by the starting factor, to select and execute an operation mode associated with the identified starting factor, and when another starting factor is generated during execution of the operation mode, the microcomputer is configured to stop execution of the operation mode and to restart to execute an operation mode associated with the other starting factor;
wherein each of the resources includes an operation clock supplied to a processor of the microcomputer;
wherein in a case in which the operation clock is equal to or less than a predetermined frequency the microcomputer is configured to monitor whether the other starting factor is generated during the execution of the operation mode associated with the identified starting factor;
wherein a first operation clock, which is one of the operation clocks, is associated with one of the operation modes; and
wherein the predetermined frequency is less than a frequency of the first operation clock.
