Abstract:
1. An integrated circuit card comprising: an input/output block for receiving external command data; a central processing unit in signal communication with the input/output block for performing a task corresponding to the received command data; a judgment block in signal communication with the central processing unit for judging whether a working time of the central processing unit reaches a reference time, after an input of the external command data is completed; and a control block in signal communication with the judgment block for operating responsive to an output of the judgment block, wherein the control block controls such that procedure data is output via the input/output block without intervention by the central processing unit whenever the working time of the central processing unit reaches the reference time, the judgment block comprising: an oscillator circuit configured to generate a clock signal; a register in signal communication with the oscillator circuit, configured to store the reference time; a counter in signal communication with the register, configured to count in synchronization with the clock signal when an input of the command data is completed; and a comparator in signal communication with the counter, for judging whether a count time of the counter reaches the reference time.
