Abstract
A clock control apparatus () receives wireless frequency information of a wireless communication apparatus () from an information communication apparatus (). Also, the clock control apparatus () detects an operation clock frequency of a main CPU (). Then, when the multiplied operation clock frequency coincides with the wireless frequency, the clock control apparatus () lowers a voltage of the operation clock of the main CPU () to a minimum voltage value at which the operation of the main CPU () is guaranteed. Alternatively, the clock control apparatus () may shift the clock frequency, or may frequency-modulate the clock frequency.
