JTAG Port Connections
If the JTAG is enabled, the JTAG will take control over a number of pins, irrespectively of the I/O
Controller configuration.

Nexus OCD AUX Port Connections
If the OCD trace system is enabled, the trace system will take control over a number of pins, irre-
spectively of the I/O Controller configuration. Two different OCD trace pin mappings are
possible, depending on the configuration of the OCD AXS register. For details, see the AVR32
UC Technical Reference Manual.
