Description
AD[31:0]
Refer to
Table 2-3
I/O
Multiplexed Address and Data
AD[31:0] is a physical address during the first clock of a PCI transaction; it is
the data during subsequent clocks.
When the CS4210 is a PCI master, AD[31:0] are outputs during the address
and write data phases, and are inputs during the read data phase of a trans-
action.
When the CS4210 is a PCI slave, AD[31:0] are inputs during the address
and write data phases, and are outputs during the read data phase of a
transaction.
C/BE[3:0]#
65, 53, 41,

I/O
Bus Command and Byte Enables
Multiplexed bus command and byte enables.
FRAME#
43
I/O
Cycle Frame
Driven by the initiator to indicate the beginning and duration of an access.
IRDY#
44
I/O
Initiator Ready
Indicates that the initiator is ready to complete the current data phase of the
transaction.
TRDY#
45
I/O
Target Ready
Indicates that the current data phase of the transaction is ready to be com-
pleted.
STOP#
48
I/O
Stop
Indicates that the current target is requesting the initiator to stop the current
transaction.
DEVSEL#
47
I/O
Device Select
When actively driven, DEVSEL# indicates the driving device has decoded
its address as the target of the current access.
IDSEL
29
I
Initialization Device Select
Used as a chip select during configuration read and write transactions.
PERR#
49
I/O
Parity Error
Used for reporting data parity errors during all PCI transactions except a
Special Cycle.
SERR#
51
I/O
System Error
Used for reporting address parity errors, data parity errors on the Special
Cycle command, or any other system error where the result will be cata-
strophic.
PAR
52
I/O
Parity
PAR is even parity across AD[31:0] and C/BE[3:0]. PAR is an input when
AD[31:0] are inputs and is an output when AD[31:0] are outputs.
PREQ#

O
PCI Bus Request
PCI bus request to PCI bus arbiter.
PGNT#
14
I
PCI Bus Grant
PCI bus grant from PCI bus arbiter.
INTA#

O
Interrupt A
1394 OpenHCI PCI interrupt.
