A standard 20-pin JTAG connector is implemented on the SAM3U-EK for any ARM JTAG emulator con-
nection, such as SAM-ICE.
Note that the NRST net is connected to the system button BP1, and is also used to reset the LCD mod-
ule. 0-Ohm resistor R75 may be removed in order to isolate the JTAG port from the system reset signal.
The SAM3U-EK includes a WOLFSON codec WM8731 for digital sound input and output. This interface
includes audio jacks for:
