ZigBEE
SAM3S has a 10-pin male connector for the RZ600 ZigBEE module.
Note:
0 Ohm resistors have been implemented in series with the PIO lines that are used else-
where in the design, thereby enabling their individual disconnection, should a conflict occur
in your application.

PIO Expansion
The SAM3S product features three PIO controllers, PIOA, PIOB and PIOC, which are multiplexed with
the I/O lines of the embedded peripherals. Each PIO Controller controls up to 32 lines (16 for PIOB).
Expansion ports J12, J13 and J14 provide PIO lines access for customer defined usage.
