Internal Registers
Node Identification Register
The Node Identification register contains the address of the node on which the OHCI resides, and indicates the
valid node number status. The 16-bit combination of the busNumber field (bits 15:6) and the NodeNumber field
(bits 5:0) is referred to as the node ID.

This bit indicates whether or not the FW322 has a valid node number. It is cleared
when a 1394 bus reset is detected and set when the FW322 receives a new node
number from the PHY core.
This bit is set during the bus reset process if the attached PHY core is root.
Reserved. Bits 29:28 return 0s when read.
Set if the PHY core is reporting that cable power status is OK.

when multiple 1394-compatible buses are connected via a bridge.
This number is the physical node number established by the PHY core during
self-identification. It is automatically set to the value received from the PHY core
after the self-identification phase. If the PHY core sets the nodeNumber to 63,
then software should not set the run bit of the ContextControl register for either of
the AT DMA contexts (see Table 53).
