Name

Description

31–12

Base address

Represents the base address for the inbound GPLA memory window. The number

of upper bits that the PCI bridge allows to be writable is selected through the PICMR;

see Section 9.11.1.17, “PCI Inbound Comparison Mask Registers (PICMRx).”

11–4

Hardwired to zeros. (The minimum window size allowed is 4K.)

Prefetchable

Corresponds to the prefetchable bit in the PICMR; see Section 9.11.1.17, “PCI

Inbound Comparison Mask Registers (PICMRx).”

2–1

Type

Hardwired to 00 to indicate that the address can be located anywhere in 32-bit

address space.

Memory space indicator Address is mapped to memory space (hardwired to 0).
