摘要:
The central processing unit (CPU) is allowed to utilize the temperature information signal, identifying the temperature, so as to commence an interruption processing for controlling the temperature. During implementation of the interruption processing, the CPU is designed to recognize the status of the cooling device in accordance with the status information signal. If a failure or defect is found in the cooling device, a thinned-out clock signal or a clock signal of a lower frequency is supplied to the CPU so as to suppress the operation of the CPU. Heat generated at the CPU can be suppressed. An additional hardware is not required to accompany the CPU so as to solely generate an interrupt request signal based on the status of the cooling device. The circuit structure of the temperature controller circuit can be simplified.
