Zigbee communication using PIC18F46K22 with UART communication

I have wrritten code for UART using PIC18F46K22. from UART output pins TX and RX are given to Din and Dout of Zigbee and CTS is active low signal is given to one GPIO.
can help me how to interface zigbee to micro controller.

If the Pic is a 3V device, then it is nothing more than making the connections just like you would if it was a cable.

If it is a 5V pic, then you need to use a level shifter.
