PCI Bus Interface
17.3.1.2.4
The PCI outbound window attributes registers (POWARn) define the window sizes to translate and other
attributes for the translations. The minimum window size is 4 Kbytes. The maximum window size is 16
Gbytes.
The default window attribute register, POWAR0, is shown in
POWARn registers are the same, only the reset values are different.
