Description
Indicates type 0 memory space (locatable anywhere in 32-bit
address space).
Upper 18 bits of base address of the first memory or IO aperture
*The base 18 can be configured to various aperture sizes from 2
MB to 256 MB. (See pci_setup register). Depending on aperture
size selected, various bits will be R/W or Read Only.
Bit:
256M: RO
128M: RW

RO = Read-only bits read back as zero.
Prefetchable if configured as 1.
*Value is determined by pci_setup register.
This bit indicates type 0 memory aperture.
Subsystem ID. The value for this field is provided by Philips PCI SIG
representative for Philips internal customers. External customers
will provide their own number.
Subsystem Vendor ID. The value for this field is 1131 for Philips
internal customers. External customers need to apply to the PCI
SIG to obtain a value if they do not have one already.
Indicates extended capabilities are present starting at 40.
Indicates the max latency tolerated in 1/4 microsecond for PCI
master. This value may be changed if written to before the pci_setup
register.
Indicates how long the PCI master will need to use the bus. This
value may be changed if written to before the pci_setup register.
Indicates which interrupt pin is used.
