The PI Bus is a Bi-directional and multiplexed interface with a 16bit data path to the ROM, 64DD, [[Flash]] Ram and cart RAM chips. It is used to send both the wanted address and data to and from the RCP. This is not to be confused with the serial EEPROM, CIC and RTC (real time clock) chips that go through the SI interface and PIF chip via the cartridge port as well.
