default description
The address of this node determined during self-identification. A value of 63
indicates a malconfigured bus; the link shall not transmit any packets.
When set to one, indicate that this node is the root.
Cable Power status.
Root hold-off bit. When set to one, instructs the PHY to attempt to become
the root during the next tree identify process.
Initiate bus reset. When set to one, instructs the PHY to initiate a bus reset
immediately (without arbitration). This bit causes assertion of the reset state
for 166 us and is self-clearing.
Used to configure the arbitration timer setting in order to optimize gap times
according to the topology of the bus. IEEE 1394-1995 4.3.6
constant value of seven
