13.0 External Device Pins
Table 16: External Device Pins
Pin/Bus Name Type
Function
AD[31:0]
T/S PCI Address and Data: 32 bit multiplexed address/data bus.
CBEN[3:0]
T/S
PCI Bus Command and Byte Enables: Multiplexed bus which contains byte enables for AD[31:0] or
the Bus Command during the address phase of a PCI transaction.
PCI Parity: Even Parity across AD[31:0] and C/BEN[3:0] busses. Driven one clock after address or
PAR
T/S data phases. Master drives PAR on address cycles and PCI writes. The Target drives PAR on PCI
reads.
FRAMEN
S/T/S
PCI Cycle Frame: Driven active by current PCI Master during a PCI transaction. Driven low to indicate
the address cycle, driven high at the end of the transaction.
DEVSELN S/T/S PCI Device Select. Driven by a Target that has decoded a valid base address.
CLK
IN PCI System Clock Input.
RSTN
IN PCI System Reset Input
PERRN
S/T/S
PCI Data Parity Error. Driven active by the initiator or target two clock cycles after a data parity error
is detected on the AD and C/BEN busses.
SERRN
O/D
PCI System Error: Driven active when an address cycle parity error, data parity error during a special
cycle, or other catastrophic error is detected.
IDSEL
IN PCI Initialization Device Select. Use to select a specific PCI Agent during System Initialization.
IRDYN
S/T/S
PCI Initiator Ready. Indicates the Initiator’s ability to complete a read or write transaction. Data transfer
occurs only on clock cycles where both IRDYN and TRDYN are active.
TRDYN
S/T/S
PCI Target Ready. Indicates the Target’s ability to complete a read or write transaction. Data transfer
occurs only on clock cycles where both IRDYN and TRDYN are active.
STOPN
S/T/S PCI Stop. Used by a PCI Target to end a burst transaction.
