Debugging on the AT32UC3B is facilitated by a powerful On-Chip Debug (OCD) system. The
user accesses this through an external debug tool which connects to the JTAG port and the Aux-
iliary (AUX) port. The AUX port is primarily used for trace functions, and a JTAG-based
debugger is sufficient for basic debugging.
The debug system is based on the Nexus 2.0 standard, class 2+, which includes:
In addition to the mandatory Nexus debug features, the AT32UC3B implements several useful
OCD features, such as:
The OCD features are controlled by OCD registers, which can be accessed by JTAG when the
NEXUS_ACCESS JTAG instruction is loaded. The CPU can also access OCD registers directly
using mtdr/mfdr instructions in any privileged mode. The OCD registers are implemented based
on the recommendations in the Nexus 2.0 standard, and are detailed in the AVR32UC Technical
Reference Manual.
