17 ZigBee Interface
The EK board has a 10-pin male connector for the Atmel RZ600 ZigBee module. DNP 0-ohm resistors
ha
ve
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.
