This section describes the PCI configuration space registers. These registers are shown with descending
bit numbering to correspond to the PCI standard.
Table 13-22

The registers described in this section use little-endian byte ordering.
Software running on the local processor in big-endian mode must byte-swap
the data. No byte swapping occurs when the registers are accessed from the
PCI bus.

Prefetchable. Defines whether the transactions that are translated through this window are
prefetchable on the local bus. Streaming the transactions requires the memory space to be
prefetchable.
0 Not prefetchable
1 Prefetchable
Reserved
Read transaction type. Determines the type of transaction performed on the local bus when the PCI
transaction is a read. The RTT values are described as follows:
0100 Read without snoop on system bus
0101 Read with snoop on system bus
Others reserved
Write transaction type. Determines the type of transaction performed on the local bus when the PCI
transaction is a write. The WTT values are described as follows:
0100 Write without snoop of local processor
0101 Write with snoop of local processor
Others reserved
Reserved
Inbound window size. Indicates the size of the inbound translation window. Inbound translation
window size N which is the encoded 2^(N+1) bytes window size. The smallest window is 4 Kbytes (N
= 11)
