I/O Type
Function
STOP
T17
I/O
PCI cycle stop signal. This signal is driven by a PCI
target to request the initiator to stop the current PCI
bus tranaction. This signal is used for target
disconnects and is commonly asserted by target
devices which do not support burst data transfers.
TRDY
U20
I/O
PCI target ready. TRDY indicates the primary bus
target s ability to complete the current data phase
of the transaction. A data phase is completed upon
a rising edge of PCLK where both IRDY and TRDY
are asserted. Until both IRDY and TRDY are
asserted, wait states are inserted.
