CBE
I/O Driven by an initiator to indicate a bus transaction
Indicates that a target has decoded the address
I/O presented during the address phase and is claiming
the transaction
Indicates that the target is ready to complete the
I/O
current data phase
Indicates that the initiator is ready to complete the
I/O
current data phase
Indicates that the target has requested to stop the
I/O
current transaction
Indicates that the interface is the target of a
I
configuration cycle
PCI Interrupt Signals
Indicates that LogiCORE PCI interface requests an
O
interrupt
PCI Error Signals
Indicates that a parity error was detected while the
I/O LogiCORE PCI interface was the target of a write
transfer or the initiator of a read transfer
Indicates that a parity error was detected during an
I/O
address cycle, except during special cycles
PCI Arbitration Signals
Indicates to the arbiter that the LogiCORE PCI
O
initiator requests access to the bus
Indicates that the arbiter has granted the bus to the
I
LogiCORE PCI initiator
PCI System Signals
PCI bus reset signal is used to bring PCI-specific
I registers, sequences, and signals to a consistent
state
I PCI bus clock signal
Input from PCI Bus REQ_N available at top-level as
O
output from bridge
Input from PCI Bus FRAME_N availalble at top-level
O
as output from bridge
