Abstract
A clock control apparatus (3) receives wireless frequency information of a wireless communication apparatus (6) from an information communication apparatus (5). Also, the clock control apparatus (3) detects an operation clock frequency of a main CPU (4). Then, when the multiplied operation clock frequency coincides with the wireless frequency, the clock control apparatus (3) lowers a voltage of the operation clock of the main CPU (4) to a minimum voltage value at which the operation of the main CPU (4) is guaranteed. Alternatively, the clock control apparatus (3) may shift the clock frequency, or may frequency-modulate the clock frequency.
Claims18
A data communication apparatus connected to a wireless communication apparatus for executing a data communication via a wireless line, comprising:
- an information communicator which communicates with the wireless communication apparatus and receives operation condition information of the wireless communication apparatus;
- a clock generator which generates a clock;
- and
- a clock controller for performing an clock control operation wherein the clock controller controls the clock generator in response to the operation condition information so that a multiplied frequency of the clock gives no disturbance to the operation of the wireless communication apparatus.
