17.3.1.3
The inbound address translation and mapping unit controls the mapping of transactions from the external
PCI address space to the internal platform address space. The inbound ATMU is comprised of four
windows—a configuration window and three general translation windows. The configuration window has
higher priority than all other inbound ATMU windows and takes precedence over them if there is an
overlap.
Each window contains the following:

Bits
A base address, which points to the beginning of the window in the external PCI address map. The
base address of each window is also accessible by PCI configuration transactions as base address
registers within the PCI configuration header, as shown in
or updated equivalently through the ATMU memory map or through PCI configuration
transactions to the PCI configuration header.
A translation address, which specifies the upper order bits of the transaction in the local address
space.
A set of attributes including window size and internal transaction attributes.
