OHCI Base Address Register
The OHCI Base Address register is programmed with a base address referencing the memory-mapped OHCI con-
trol. When BIOS writes all 1s to this register, the value read back is FFFF F000h, indicating that 4 Kbytes of mem-
ory address space are required for the OHCI registers.

OHCI Register Pointer. Specifies the upper 20 bits of the 32-bit OHCI
base address.
OHCI Register Size. This field returns 0s when read, indicating that
the OHCI registers require a 4 Kbyte region of memory.
OHCI Register Prefetch. This bit returns 0 when read, indicating that
the OHCI registers are not prefetchable.
OHCI Memory Type. This field returns 0s when read, indicating that
the OHCI Base Address register is 32 bits wide and mapping can be
done anywhere in the 32-bit memory space.
OHCI Memory Indicator. This bit returns 0 when read, indicating that
the OHCI registers are mapped into system memory space.
Built-In Self-Test. The FW322 does not include a built-in self-test;
thus, this field returns 00h when read.
PCI Header Type. The FW322 includes the standard PCI header, and
this is communicated by returning 00h when this field is read.
