The power-up reset value of this register =

.
NOTE:
The power-up reset value shown above assumes one node on the bus only. A
P1394a compliant Phy is assumed to be attached to the TSB12LV32. If a
1394-1995 Phy is attached to the TSB12LV32 link, the NODECNT filed will be 0.
This is due to the fact that a 1394-1995 compliant Phy does not report its self-ID
packet back to the local link.

NRIDVAL
Valid
R
When set, NRIDVAL indicates that the Node ID, IRM Node ID,
Node Count, and Root information are valid. This bit is read
only.

NODECNT
Node count
R
NODECNT contains the number of nodes detected in the
system. This field is loaded with 1 following a power-on reset.
The NODECNT field is read only.
8
ROOT
Root
R
Root is set when the current node is the root node. This bit is
read only.
9
CONTENDER
Contender
R
Contender contains the status of the TSB12LV32 CONTNDR
terminal. This bit is read only.

IRMNODEID
IRM node
identification
R
IRMNODEID is the isochronous resource manager node
identification. If there is no IRM node present on the bus,
these bits will be equal to 3Fh. These bits are read only.

25
BUSNUMBER
Bus number
R/W
BUSNUMBER is the 10-bit IEEE-1212 bus number. These
bits are set to 3FFh when RBUSNUM is set and there is a bus
reset.
26
–
31
NODENUMBER
Node
number
R/W
NODENUMBER is the node number of the current node.
These bits are automatically updated following a bus reset. To
change the node number of this node (spoofing), the
TESTMODE terminal must be set high.
