4.3.20 ZigBee
The SAM4E-EK has a 10-pin male connector for the RZ600 ZigBee module.
Note: 0Ω resistors have been implemented in series with the PIO lines that are used elsewhere in the design, thereby
enabling their individual disconnection, should a conflict occur in your application.

The SAM4E-EK product features three PIO controllers, PIOA, PIOB, PIOC and PIOD, which are multiplexed with the
I/O lines of the embedded peripherals. Each PIO Controller controls up to 32 lines (15 for PIOB and 6 for PIOE).
Expansion ports J15, J16, J17 and J18 provide PIO lines access for customer usage.
