3.6.4 Configuration and test points
3.6.4.1 Configuration
The J8.1 and J8.2 pins are configurable through the J44 header. Refer to
, for a description of the possible
configurations.
3.6.4.2 Test points
None.
3.6.4.3 Special consideration when using the expansion headers
The J8+J44 expansion headers gather signals multiplexed with the JTAG signals on
J8.1, J8.2, and J8.5. For this reason, JTAG debugging is not possible when an
external component is connected to these pins of the WLESS header. See also
Section

The J14 and J15 headers gather all GPIO signals of the Atmel AT32UC3L064.
Obvious care should be taken when accessing pins that are being used by another

3.7 USB interface
The USB interface on the Atmel AT32UC3L-EK offers USB communication
capabilities to the AT32UC3L064 through the on-board Atmel AT32UC3B1256
device.
