I/O
PCI Address/Data Bus.
A time-multiplexed
address data bus.
I/O
PCI Command/Byte
Enable.
Defines the type
of AD bus transaction
type.
Cycle Frame.
A PCI
transaction begins and
ends with the FRAME
signal.
Initiator Ready.
An active
low indicates the cycle
initiator is ready to send
or receive data.
Target Ready.
An active
low indicates that the
target is read to complete
the current transaction.
Device Select.
An active
low indicates the target
has decoded its address.
STOP.
An active low
indicates the target wants
the initiator to stop data
during the current data
phase.
Parity.
Generates an
even parity for the
AD[31.0].
Reset.
A low active signal
which resets the PCI
device.
Interrupt.
An active low
signals in interrupt to the
CPU.
Clock.
The clock that
drives the PCI timing.
Grant.
An active low
signals the master has
access to the PCI bus.
Request.
An active low
indicates the master
wants access to the PCI
bus.

Type
Description
I/O
Clock Run.
An active low
signal used for power
management on
motherboards only. It is
not assigned a pin on the
PCI connector.
Power Management
Event.
An active low
signal used for power
management for add in
cards or motherboards. It
is assigned a pin on the
PCI connector.
Terminal Count.
This
input is asserted by the
DMA controller to indicate
the end of a DMA
transfer. The signal is
only effective during a
DMA access cycle.
Initialization Device
Select.
An active high
allows reads to the PCI
devices configuration
registers.
