Clock input for the PCI core clock domain (0 to 66 MHz)
Multiplexed address/data bus
Command and byte enable bus
Active-low PCI reset signal. This is an output if IXP2400 is
the bus host.
It is an input if IXP2400 is not the bus host.
The direction of this pin is controlled by the CFG_RSTDIR
pin.
Receives interrupt from another PCI device if the IXP2400
is the bus host; otherwise used as an interrupt to the host
processor.
Receives interrupt from another PCI device if the IXP2400
is the bus host.
Transaction in progress indication
Termination with retry or disconnect-with-data
Initiator ready on data phase
Target ready on data phase
Device select indication
IdSel signal to the IXP2400; used during the configuration
cycle
Bus requests from external master 0, used when the
IXP2400 is arbiter/host; the IXP2400’s request output to
external arbiter when not a host.
Bus requests from external master 1, used when the
IXP2400 is arbiter/host.
Bus grant output to external master 0 when this chip is
arbiter/host; grant input to the IXP2400 from external arbiter
when not a host.
Bus grants to external master 1, used when the IXP2400 is
arbiter/host
Indication that a 64-bit data phase is desired. During reset,
driven low by the system to indicate 64-bit capability.
Indicates that a 64-bit data phase is accepted.
Parity on AD[31:0]
Parity on AD[63:32]
Parity error detected on incoming data
Parity error on address phase, illegal command, etc. When
this chip is the host SERR is an input; when using with an
external host, SERR is an output.
