Abstract
Abstract A method and corresponding apparatus retrieves data from at least one joystick connected to a video game machine by generating a data locking signal to lock multiple bits of data in at least one joystick in response to a data read signal supplied by the video game machine; generating a data retrieving signal including a plurality of consecutive pulses to retrieve multiple bits of data in the joystick in response to the data read signal; transferring consecutively the multiple bits of data from the joystick to a data register in response to the data retrieving signal wherein the plurality of consecutive pulses is employed to retrieve the multiple bits of data; and reading the multiple bits of data directly from the data register in response to the data read signal by the video game machine. The apparatus using the above method comprises a timing generator for generating a data locking signal to lock multiple bits of data in the joystick or joysticks and a data retrieving signal including a plurality of pulses to consecutively retrieve the multiple bits of data from the joystick in response to a data read signal supplied by video game machine; and a data register for consecutively receiving and storing the multiple bits of data, and outputting the multiple bits of data in parallel according to the data read signal.
