The SAM9N12/CN11 has a high-speed Multimedia Card Interface (MCI). It is used as a 4-bit interface 
connected to an SD card slot.

Figure 4-19.  SD Card

The EK board has a 10-pin male connector for the Atmel RZ600 ZigBee module. DNP 0-ohm resistors 
have been implemented in series with the PIO lines that are used elsewhere in the design. Thereby, it 
enables their individual disconnection, should a conflict occur in user application.
