BAR Table (BAR1) BAR type and size
BAR1 size and type mapping (I/O space (1), memory space. BAR0
and BAR1 can be combined to form a 64-bit prefetchable BAR. BAR0
and BAR1 can be configured separate as 32-bit non-prefetchable
memories.)
BAR Table (BAR2)
(3)
BAR type and size
BAR2 size and type mapping (I/O space (1), memory space. BAR2
and BAR3 can be combined to form a 64-bit prefetchable BAR. BAR2
and BAR3 can be configured separate as 32-bit non-prefetchable
memories.) (2)
BAR Table (BAR3)
(3)
BAR type and size
BAR3 size and type mapping (I/O space (1), memory space. BAR2
and BAR3 can be combined to form a 64-bit prefetchable BAR. BAR2
and BAR3 can be configured separate as 32-bit non-prefetchable
memories.)
BAR Table (BAR4)
(3)
BAR type and size
BAR4 size and type mapping (I/O space (1), memory space. BAR4
and BAR5 can be combined to form a 64-bit BAR. BAR4 and BAR5
can be configured separate as 32-bit non-prefetchable
memories.) (2)
BAR Table (BAR5)
(3)
BAR type and size
BAR5 size and type mapping (I/O space (1), memory space. BAR4
and BAR5 can be combined to form a 64-bit BAR. BAR4 and BAR5
can be configured separate as 32-bit non-prefetchable memories.)

PCIe Read-Only Registers
Device ID
0x000
0x0004 Sets the read-only value of the device ID register.
Subsystem ID
0x02C (3)
0x0004 Sets the read-only value of the subsystem device ID register.
Revision ID
0x008
0x01 Sets the read-only value of the revision ID register.
Vendor ID
0x000
0x1172
Sets the read-only value of the vendor ID register. This parameter
can not be set to 0xFFFF per the PCI Express Specification.
Subsystem vendor ID
0x02C (3)

Sets the read-only value of the subsystem vendor ID register. This
parameter can not be set to 0xFFFF per the PCI Express Base
Specification 1.1 or 2.0.
Class code
0x008
0xFF0000 Sets the read-only value of the class code register.
Base and Limit Registers
Input/Output (5)
Disable
16-bit I/O addressing
32-bit I/O addressing
Specifies what address widths are supported for the
IO base
and
IO limit
registers.
