ABSTRACT:
The present invention relates to a clock control circuit apparatus including a first oscillation circuit for generating a first clock signal and a second oscillation circuit for generating a second clock signal and capable of, when the two clock signals are put to use, improving the reliability of oscillation operations thereof. In the clock control circuit apparatus, a sub-clock correction unit corrects an oscillation frequency of a sub-clock signal on the basis of a main clock signal, while a main clock monitoring unit monitors an oscillation state of the main clock signal on the basis of the sub-clock signal.
