Claim Text:
1. A microcomputer comprising: a register that stores division ratio setting information; a frequency divider that determines first and second division ratios based on the division ratio setting information, frequency-divides a first clock having a first frequency at the first division ratio, and frequency-divides a second clock having a second frequency at the second division ratio; and a CPU (central processing unit) connected to the register and the frequency divider, wherein the first frequency is lower than the second frequency, wherein when the division ratio setting information indicates a frequency higher than the first frequency, the first division ratio is set to 1 and the second division ratio is set based on the division ratio setting information, and wherein when the division ratio setting information indicates a frequency equal to or lower than the first frequency, the first and second division ratios are determined in such a manner that a frequency of the first clock that is frequency-divided at the first division ratio and a frequency of the second clock that is frequency-divided at the second division ratio are made equal to each other.
