Peripheral Functions
JTAG Port Connections
Nexus OCD AUX Port Connections
Refer to the
ties of the TWI, 5V Tolerant, and SMBUS pins.
Each GPIO line can be assigned to one of several peripheral functions. The following table
describes how the various peripheral functions are selected. The last listed function has priority
in case multiple functions are enabled on the same pin.
Table 3-2.
If the JTAG is enabled, the JTAG will take control over a number of pins, irrespectively of the I/O
Controller configuration.
Table 3-3.
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.
