ORCAOR3TP12 FPSC
Embedded Master/Target PCI Interface
Data Sheet
March 2000

L Lucent Technologies Inc.
PCI Bus Core Master Controller
Detailed Description
(continued)
Termination
Once initiated, Master write operations will continue on
the PCI bus until either all write data is sent, an abort
occurs (either Master or Target), or the PCI bus’ reset
signal (
rstn
) is asserted. During aborts, the Master
address and write data FIFOs will be cleared, and the
FPGA application will be notified by the assertion of
fpga_msyserror
.
If the Master write transaction is terminated with a retry
or disconnected by the external Target before all data
has been transferred, the Master will initiate another
Master write operation, continuing from that point using
a stored address pointer.
On the Master FIFO interface, the FPGA application
identifies the last data word by asserting
mwlastcycn
.
When this data word is transferred to the PCI bus, the
Master will terminate the PCI transaction normally. The
Master will inform the FPGA application of completion
by deasserting
ma_fulln
.
Reset
The FPGA application can apply a reset signal to place
the Master FIFO interface logic in a known state, which
clears all FIFOs and
mstatecntr
. The reset signal,
mfifoclrn
, is asynchronous and therefore should be
asserted for a minimum of one clock cycle and deas-
serted for a minimum of one clock cycle before continu-
ing. This is not recommended to assert
mfifoclrn
while
a current PCI transaction is in progress (
ma_fulln
asserted), since proper PCI bus termination is not
guaranteed. Only PCI
rstn
will reset the internal Master
PCI state machines, while a PCI transaction is in
progress.
