PCI interface
A/D[31:0] - PCI Address Data (bi-directional)
Address and Data are multiplexed on the same PCI pins.
During the address phase, A/D[31::00] contain a physical address (32 bits). For I/O, this is a byte
address; for configuration and memory, it is a DWORD address. During data phases,
A/D[07::00] contain the least significant byte and A/D[31::24] contain the most significant byte.
C/BE[3:0]* - PCI Bus Command and Byte Enables (bi-directional)
During the address phase of a transaction, C/BE[3::0]* define the bus command. During the data
phase, C/BE[3::0]* are used as Byte Enables. The Byte Enables are valid for the entire data
phase.
PAR - Parity (bi-directional)
The number of "1"s on A/D[31::00], C/BE[3::0]*, and PAR equals an even number
FRAME* - Cycle Frame (bi-directional)
It is driven by the current master to indicate the beginning and duration of an access. FRAME* is
asserted to indicate a bus transaction is beginning. While FRAME* is asserted, data transfers
continue. When FRAME* is deasserted, the transaction is in the final data phase or has
completed.
IRDY* - Initiator Ready (bi-directional)
IRDY* indicates the initiating agent’s ability to complete the current data phase of the transac-
tion. IRDY* is used in conjunction with TRDY*. During a write, IRDY* indicates that valid data is
present on A/D[31::00]. During a read, it indicates the master is prepared to accept data.
TRDY* - Target Ready (bi-directional)
TRDY* indicates the target agent’s (selected device’s) ability to complete the current data phase
of the transaction. TRDY* is used in conjunction with IRDY*. During a read, TRDY* indicates that
valid data is present on AD[31::00]. During a write, it indicates the target is prepared to accept
data.
STOP* - Stop (bi-directional)
STOP* indicates the current target is requesting the master to stop the current transaction.
PCI_LOCK* - Lock (bi-directional)
PCI_LOCK* indicates an atomic operation to a bridge that may require multiple transactions to
complete.
IDSEL - Initialization Device Select (input)
Initialization Device Select is used as a chip select during configuration read and write
transactions.
DEVSEL* - Device Select (bi-directional)
When actively driven, indicates the driving device has decoded its address as the target of the
current access. As an input, DEVSEL* indicates whether any device on the bus has been
selected.
REQ* - PCI bus request (output)
REQ* indicates to the arbiter that this agent desires use of the bus. This is a point-to-point sig-
nal. Every master has its own REQ* which must be tri-stated while RST* is asserted.
GNT* - PCI Bus Grant (input)
GNT* indicates to the agent that access to the bus has been granted. This is a point-to-point sig-
nal. Every master has its own GNT* which must be ignored while RST* is asserted.
PCI_CLK - PCI clock (input)
