Overview
The SAM3U Series Microcontrollers feature a number of complementary debug and test
capabilities. The Serial Wire/JTAG Debug Port (SWJ-DP) combining a Serial Wire Debug Port
(SW-DP) and JTAG Debug (JTAG-DP) port is used for standard debugging functions, such as
downloading code and single-stepping through programs. It also embeds a serial wire trace.
