3.3.1 Overview
Figure 3-8. Atmel AT32UC3L-EK programming and debugging interface logical view.
The main programming and debugging interface of the AT32UC3L-EK is meant to
program and debug the Atmel AT32UC3L064. There are two debug interfaces
available on the AT32UC3L064: the JTAG interface and the aWire interface (single
pin debug system), both accessible through the J9 connector.
NOTE There is another programming and debugging interface block on the kit, but it is
related to the Atmel AT32UC3B1256 chip in charge of USB communication (refer to
Section 3.7, USB interface).
