PCI Express Interface Controller
18.3.5.2
There are differences between RC and EP implementations of inbound ATMU registers as described in the
following sections.
18.3.5.2.1
All base address registers (BARs) reside in the PCI Express type 0 configuration header space which is
accessible via PEX_CONFIG_ADDR/PEX_CONFIG_DATA mechanism. Note that host software must
program these BAR using configuration type 0 cycles. There are 4 inbound BARs.
The PCI Express controller does not implement a shadow of the inbound BARs in the memory-mapped
register set. However, when there is a hit to the BAR(s), the PCI Express controller uses the corresponding
translation and attribute registers in the memory-mapped register set for the translation. If the transaction
hits multiple BARs, then the lowest-numbered BAR will be used.

Default inbound window BAR0 at configuration address 0x10 (32-bit). Also known as
PEXCSRBAR. This is a fixed 1-Mbyte window used for inbound memory transactions that access
memory-mapped registers.
Inbound window BAR1 at configuration address 0x14 (32-bit)
Inbound window BAR2 at configuration address 0x18-0x1c (64-bit)
Inbound window BAR3 at configuration address 0x20-0x24 (64-bit)

The smallest window size is 4 Kbytes. Note that for the default window (window 0), the outbound window
size may be programmed less than the 64-Gbyte maximum. However, accesses that miss all other windows
and hit outside the default window will be aliased to the default window.
