Internal Registers
PCI OHCI Control Register
The PCI OHCI Control register is defined in Section A.3.7 of the 1394 Open Host Controller Interface
Specification and provides a bit for big-endian PCI support. Note that the GLOBAL_SWAP bit is loaded from the
serial EEPROM on powerup.

Reserved. Bits 31:1 return 0s when read.
When this bit is set, all quadlets read from the FW322 as well as any
data written to the PCI bus by the FW322 is byte swapped. This
excludes PCI Config registers and CardBus Function Event registers
(they are not swapped under any circumstances). However, OHCI
registers are byte swapped when this bit is set.
Next Item Pointer. The FW322 supports only one additional capability
that is communicated to the system through the extended capabilities
list; thus, this field returns 00h when read.
Capability Identification. This field returns 01h when read, which is
the unique ID assigned by the PCI SIG for PCI power management
capability.
