-The PC Engine uses the same chip as the [[megadrive_genesis_controller_3|Genesis 3-button pad]]: the [[chips:​74157]]. ​ Basically, the console sends a high/low signal on a select line, triggering four different signals. ​ The buttons (I, II, ST, SL) are returned when the select line is LOW, the d-pad is returned when select is HIGH.+The PC Engine uses the same chip as the [[megadrive_genesis_controller_3|Genesis 3-button pad]]: the [[chips:​74157]]. ​ Basically, the console sends a high/low signal on a select line, triggering four different signals. ​ The buttons (I, II, RN, SL) are returned when the select line is LOW, the d-pad is returned when select is HIGH.
  
 All the TG and most of the PCE pads also had auto-fire, which required the use of another chip: the [[chips:​74163]]. ​ This simple binary counter is advanced by the select line, and every fourth or eighth '​pulse'​ it activates the I and II buttons, effectively creating two rapid-fire speeds. All the TG and most of the PCE pads also had auto-fire, which required the use of another chip: the [[chips:​74163]]. ​ This simple binary counter is advanced by the select line, and every fourth or eighth '​pulse'​ it activates the I and II buttons, effectively creating two rapid-fire speeds.
