Global Unique ID Registers are Read Only
Once set, this bit cannot be cleared except by PCI
Reset. The GUID registers are located in memory in
the 1394 register space.

Note:
A default value of 0000 for bits 3-0 indicates that the
1394 interface is connected to a 1394a-compliant
PHY.

1394 Function Hidden
If this bit is set, the 1394 function will be
hidden. All subsequent reads or writes to this
configuration space will then cause a master
abort to be generated. This bit can only be
cleared by a PCI reset.
Offset FB-F8 – Manufacturer ID ................................... RO
