The PCI outbound window base address registers (POWBARn) point to the beginning of each translation
window in the local 32-bit address space. Addresses for outbound transactions are compared to the
appropriate bits in these registers, according to the sizes of the windows. If a transaction does not fall
within one of these windows, the default translation and mapping is used. The default window is always
enabled and used when the other windows miss.
Note that POWBAR0 (for outbound ATMU window 0) is not used, because window 0 is the default
window used when no other windows match. POWBAR0 may be read from and written to, but the value
is ignored.
The format of the POWBARn is shown in
