Trace operation
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
according to the Nexus standard. The messages are buffered in a 16-frame transmit queue, and
are output on the AUX port one frame at a time.
