MEMORY BASE REGISTER – OFFSET 20h
Bit
Function
Type
Description
3:0
R/O
Lower four bits of register are read only and return 0.
Reset to 0
15:4
Memory Base
Address [15:4]
R/W
Defines the bottom address of an address range for the bridge to
determine when to forward memory transactions from one interface
to the other. The upper 12 bits correspond to address bits [31:20]
and are writable. The lower 20 bits corresponding to address bits
[19:0] are assumed to be 0.
Reset to 0
14.1.18
MEMORY LIMIT REGISTER – OFFSET 20h
Bit
Function
Type
Description
19:16
R/O
Lower four bits of register are read only and return 0.
Reset to 0
31:20
Memory Limit
Address [31:20]
R/W
Defines the top address of an address range for the bridge to
determine when to forward memory transactions from one interface
to the other. The upper 12 bits correspond to address bits [31:20]
and are writable. The lower 20 bits corresponding to address bits
[19:0] are assumed to be FFFFFh.
14.1.19
PEFETCHABLE MEMORY BASE REGISTER – OFFSET 24h
Bit
Function
Type
Description
3:0
64-bit addressing
R/O
Indicates 64-bit addressing
0000: 32-bit addressing
0001: 64-bit addressing
Reset to 1
15:4
Prefetchable
Memory Base
Address [31:20]
R/W
Defines the bottom address of an address range for the bridge to
determine when to forward memory read and write transactions from
one interface to the other. The upper 12 bits correspond to address
bits [31:20] and are writable. The lower 20 bits are assumed to be 0.
