Game Port I/O Flow Chart
The Game port integrates four timers for two joysticks. The IT8710F allows the Game Port base address to be
located within the host I/O address space 100h to 0FFFh. Currently, most game software assume that the
Game (or Joystick) I/O port is located at 201h.
A write to the Game port base address will trigger four timers. A read from the same address returns four bits
that correspond to the output from the four timers, and other four status bits corresponding to the joystick
buttons will also be returned. A button value of 0 indicates that the button is pressed. When the Game port
base address is written, the X/Y timer bits go high. Once the Game port base address is written, each timer
output remains high for a duration of time determined by the current joystick position.
