Error
Auxiliary Port Control Register (AXC)
The error message indicates various errors that can occur during trace or debugging. Table 9-21
lists the various errors that can be reported, along with the associated ECODE.
If trace messages are lost because of insufficient space in the Transmit Queue, an error mes-
sage is transmitted, followed by a synchronization message, as soon as space is available in the
Transmit Queue.
Table 9-20.
Table 9-21.
Table 9-22 shows the description of the Auxiliary Port Control Register. This register allows
greater flexibility in controlling the operation of the AUX port than specified by the Nexus stan-
