PCI

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

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

South Bridge serial
