Signal descriptions

  • OUT0: Output to the controller, used on standard controllers to latch the current button state. Written manually via JOYOUT D0 or automatically during autoread.
  • joypad 1 /OE, joypad 2 /OE: Clocks the joypad. Asserted when reading JOYSER0 (joypad 1) or JOYSER1 (joypad 2) and during autoread.
  • joypad 1 D1..0: Controller input read manually via JOYSER0 D1..0 or automatically via JOY1 (D0) and JOY2 (D1).
  • joypad 2 D1..0: Controller input read manually via JOYSER1 D1..0 or automatically via JOY3 (D0) and JOY4 (D1).
  • joypad IO D7..6: Bidirectional IO bits accessed through RDIO and WRIO D7..6. D7 also functions specially as a light pen input via OPHCT and OPVCT.
