8.6 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 PIO configuration. Two different OCD trace pin mappings are possible,
depending on the configuration of the OCD AXS register. For details, see the AVR32 AP Techni-
cal Reference Manual.
