NAME
DESCRIPTION
0
Arbitration reset gap
Indicates that the phy has detected that the bus has been idle for an arbitration reset gap time (this time is
defined in the P1394 standard). This bit is used by the link in its busy/retry state machine.
Indicates that the phy has detected that the bus has been idle for a subaction gap time (this time is defined
in the P1394 standard). This bit is used by the link to detect the completion of an isochronous cycle.
Indicates that the phy has entered the bus reset state.

Address
Indicates that the phy stayed in a particular state for too long a period, which is usually the effect of a loop
in the cable topology, or that the cable power has dropped below the threshold for reliable operation.
These bits hold the address of the phy register whose contents will be transferred to the link.
