PCI

PCI pads - as seen on COK-002
note: Two circular pads in the bottom right corner are for southbridge serial

Communication Processor (PCI) connector beneath the PCIe x4 connector on a TMU-520

PCI

Bus, resembling Conventional PCI 2.3, directly connected to South Bridge, with 80 exposed pads

Activated by setting offset 0x48C02 in SC EEPROM to 0x00 or 0x03:

• 0x00 is for IFB (InterFace Board, used by CEB)
• 0x03 is for Communication Processor (PIF5, used by DEH-R10XX and DECR-1000)
  • Does also have support for all retail platforms (e.g. COK-001, VER-001 or RTX-001)

Supported devices:

Device ID	Device "Name"	Firmware

Major differences from PCI standard:

• smaller formfactor (80 pin, instead of miniPCI 100P-type I/II or MiniPCI 124P-Type III)
• no use of miniPCI standard sideband signals for audio and communications
• no support of the miniPCI standard CLKRUN# signal defined in the PCI Mobile Design Guide
• no support for optional JTAG signals, nor for the 64-bit PCI extension defined in the PCI Local Bus Specification
