A data wireless apparatus includes a receiving section for receiving a radio frequency (RF) signal to produce RF data from the received RF signal, an error detecting section for detecting an error of the RF data, an oscillator which generates a signal, a dividing section for dividing a frequency of the signal from the oscillator in accordance with a frequency division value to produce a clock signal, a data memory section for storing data, a connection state detecting section for detecting whether or not an information processing apparatus is connected to the data wireless apparatus, and an accessing section having a plurality of drive capability levels, for accessing to the data memory section with a drive capability level determined in accordance with a drive capability switching signal. In operation, one of a plurality of predetermined values is provided as the frequency division value to the dividing section based on an error detected by the error detecting section. |
