Nexus OCD AUX port connections

If the OCD trace system is enabled, the trace system will take control over a number of pins, irre-

spective of the GPIO configuration. Three differents OCD trace pin mappings are possible,

depending on the configuration of the OCD AXS register. For details, see the AVR32 UC Tech-

nical Reference Manual.
