Key Terms

Initiator —Or Master —the bus and initiates the data transferOwns —Every Initiator must also be a Target

Target —Or Slave —Target of the data transfer (read or write)

Agent —Any initiator/target or target on the PCI bus

PCI Signals

RST# —Asynchronous reset —PCI device must tri-state all I/Os during reset

Transaction Control Initiator Signals



FRAME# – I/O —Signals the start and end of a transaction

RIYD # –/I — O I“R-

Transaction Control Target Signals DEVSEL# – I/O —Device select —Part of PCI’s distributed address decoding –Each target is responsible for decoding the address with each transaction –When a target recognizes its address, it asserts DE claim the corresponding transaction
