1. A wireless communication terminal controlling an input detecting operation by using an interrupt handler, the wireless communication terminal comprising:

  • a general purpose input output (GPIO) port for receiving an input from a user, changing a state of the GPIO port according to the input and transmitting a signal when the input is received from the user;

    a first timer for providing a first predetermined interval of performing the input detecting operation;

    a second timer for providing a second predetermined interval of activating the interrupt handler;

    a controlling unit for activating the interrupt handler to receive the signal from the GPIO port and generate an interrupt by receiving the signal for activating the first timer and the second timer, un-activating the interrupt handler when the interrupt handler generates the interrupt, performing the input detecting operation based on the first predetermined interval, re-activating the interrupt handler based on the second predetermined interval for stopping to perform the input detecting operation.
