11.8
11.8.1
The PCI interface does not implement lock#, sbo, and
sbone pins. Consequently, it is possible for both the
DSPCPU and external PCI initiators to write to a critical
memory section simultaneously. Software must imple-
ment policies to guarantee memory coherency.
11.8.2
PNX1300 does not implement the PCI expansion ROM
capability.

11.8.3
The PCI interface does not implement the PCI cacheline-
wrap address mode for external PCI initiators that ac-
cess PNX1300 SDRAM.
11.8.4
Only single-data-phase transactions to configuration and
I/O spaces are supported. The byte-enable signals se-
lect the byte(s) within the addressed word.
11.8.5
External initiators can access PNX1300 MMIO registers
only as full words. The byte-enable signals have no ef-
fect on the data transferred. External initiators must read
and write all four bytes of MMIO registers.
