MICROCONTROLLER AND CONTROL METHOD OF THE SAME

The invention provides a microcontroller and a control method of the same. To provide a microcontroller that suppresses increase of power consumption during debugging, a microcontroller according to the present invention includes a first signal processing circuit, a second signal processing circuit that performs signal processing in the same manner as the first signal processing circuit, a comparing circuit that compares a processing result of the first signal processing circuit and a processing result of the second signal processing circuit with each other, and outputs an error signal when anerror is detected, a suppressing signal input unit that receives a suppressing signal for suppressing an operation of the second signal processing circuit and an operation of the comparing circuit, asuppressing circuit that receives the suppressing signal from the suppressing signal input unit and suppresses the operation of the second signal processing circuit and the operation of the comparingcircuit, and a pseudo erro
