Japanese Patent JP3122304
Kind Code:
B2
Abstract:
PURPOSE:To effectively use an existent mouse connection port to connect a joy stick by enabling the operation input of the joy stick when it is recognized that the joy stick is connected to the connection port that is common to a mouse and the joy stick. CONSTITUTION:Respective signal lines on pins P4 and P5 which pass and receive a clock signal CLK and data DATA as signal paths that are part of a mouse/ joy stick connection port 60 are switched between the signal input terminal of a joy stick controller 33 and the signal input terminal of a keyboard controller 35. Then when it is recognized that the switching control signal of a bit b3 of an IO register 51d is '1', the signal lines on the pins P4 and P5 are connected to the signal input terminal of the joy stick controller 33 to enable the operation input of the joy stick 70. Consequently, the connection mechanism of the mouse 80 is effectively used to use one port 60 for the mouse 80 and joy stick 70 in common.
