    Abstract: A semiconductor device capable of achieving desirable communication behavior through a bus regardless of whether or not a pull-up resistor is connected on a bus line. The semiconductor device includes external pull-up determination unit and internal pull-up setting unit. The external pull-up determination unit applies a pull-down voltage through an internal pull-down resistor to the bus line, and determines whether an external pull-up resistor external to the semiconductor device is connected on the bus line on the basis of the voltage level of the bus line when the pull-down voltage is applied to the bus line. The internal pull-up setting unit stops application of the pull-down voltage, and applies a pull-up voltage through an internal pull-up resistor to the bus line if it is determined that no external pull-up resistor is connected on the bus line.

    Publication number: 20120315857
    Abstract: A wireless communication method and apparatus that produce only a small amount of transmission delay even when carrier sensing is performed. Intensity indication data indicating the radio wave intensity of a received wireless signal is generated. The intensity indication data is intermittently captured and retained. An average of the retained intensity indication data is calculated. If the average is less than or equal to a threshold, a wireless transmission operation is enabled. The average is calculated with a frequency according to the frequency of capturing of the intensity indication data. The average and the threshold are compared at a frequency corresponding to the frequency of calculation of the average.
