Pin Descriptions
PCI Bus Address Inputs / Data Input/Outputs:
These pins connect to PCI bus signals AD[31:0].
PCI Bus Command / Byte Enables: The command
signalling and byte enables are multiplexed on the
same pins. During the address phase of a
transaction, C/BE[3:0]# are interpreted as the bus
commands. During the data phase, C/BE[3:0]# are
interpreted as byte enables. The byte enables are to
be valid for the entirety of each data phase, and they
indicate which bytes in the 32-bit data path are to
carry meaningful data for the current data phase.
Cycle Frame: This input indicates to the PD6729 that
a bus transaction is beginning. While FRAME# is
asserted, data transfers continue. When FRAME# is
deasserted, the transaction is at its final phase.
Initiator Ready: This input indicates the initiating
agent’s ability to complete the current data phase of
the transaction. IRDY# is used in conjunction with
TRDY#.
