A function processing unit includes a control-signal input/output unit to
which a control signal indicating that radio data for a semiconductor
device is transmitted is input by a cable signal, and a reset-signal
input unit to which a reset signal instructing reset of the function
processing unit is input by a cable signal, and when the reset signal is
input, performs a reset process according to the reset signal. A
radio-communication processing unit includes a
radio-communication-processing-reset-signal input unit to which a radio
communication processing reset signal instructing reset of the
radio-communication processing unit is input by a cable signal, when the
radio communication processing reset signal is input, performs a reset
process according to the radio communication processing reset signal, and
receives the radio data only when the control signal is input.
