Firmware Hub Signals: These signals are muxed with LPC address signals.
Firmware Hub Signals: This signal is muxed with the LPC LFRAME# signal.
PCI Address/Data: AD[31:0] is a multiplexed address and data bus. During the first
clock of a transaction, AD[31:0] contain a physical address (32 bits). During
subsequent clocks, AD[31:0] contain data. The 82801E C-ICH drives all 0s on
AD[31:0] during the address phase of all PCI Special Cycles.
Bus Command and Byte Enables: The command and byte enable signals are
multiplexed on the same PCI pins. During the address phase of a transaction,
C/BE[3:0]# define the bus command. During the data phase, C/BE[3:0]# define the
Byte Enables.
All command encodings not shown are reserved. The 82801E C-ICH does not
decode reserved values, and therefore will not respond if a PCI master generates a
cycle using one of the reserved values.
As a target, the 82801E C-ICH can support DAC mode addressing for 44 bits.
Device Select: The 82801E C-ICH asserts DEVSEL# to claim a PCI transaction.
As an output, the 82801E C-ICH asserts DEVSEL# when a PCI master peripheral
attempts an access to an internal 82801E C-ICH address or an address destined
for the hub interface (main memory or AGP). As an input, DEVSEL# indicates the
response to an 82801E C-ICH-initiated transaction on the PCI bus. DEVSEL# is
tri-stated from the leading edge of PCIRST#. DEVSEL# remains tri-stated by the
82801E C-ICH until driven by a target device.
