Test Points
Solder Drops
Assigned PIO Lines, Disconnection Possibility
Some test points have been placed on the SAM3U-EK board for the verification of important signals.
Table 4-9. Test Points
Two solder drops have been designed on the SAM3U-EK for isolation puposes.
Table 4-10. Solder Drops
As pointed out in previous interface descriptions, 0-Ohm resistors have been inserted on the PIO lines
receiver path of the SAM3U-EK. Some PIO lines are connected to an external driver on the board. The
0-Ohm resistors allow disconnecting each of these for custom usage (through PIO expansion connec-
