trace operation
the debug session starts. The AUX port is mapped to two different locations, selectable by OCD
Registers, minimizing the chance that the AUX port will need to be shared with an application.
Debug tools utilizing the AUX port should connect to the device through a Nexus-compliant Mic-
tor-38 connector, as described in the AVR32UC Technical Reference manual. This connector
includes the JTAG signals and the RESET_N pin, giving full access to the programming and
debug features in the device.

Trace features are enabled by writing OCD registers by JTAG. The OCD extracts the trace infor-
mation from the CPU, compresses this information and formats it into variable-length messages
