* Pins 14 & 39 on the cartridge connector are missing contacts, thus these pins only apply to the EXT connector on the bottom of the console.
* Pin 18 is bi-directional data between the CIC and PIF.
* Pin 19 is a ~1.95 MHz clock driven by the PIF, used for both the CIC's CPU clock (pin 11) and EEPROM communication.
* Pin 21 is PIF Channel 5, via PIF pins 23 & 24.
* Pin 43 is the clock associated with pin 18's data, and is always driven by the PIF. It only pulses when the PIF needs to send or receive data.
