connected to an external switch in the application. When the pin is
triggered the device will wake up and send a wake up message to all the
devices on the network. When not in use, this pin should be pulled Up or
Down
Input,
Allows automatic frequency hoping whenever an interference signal is

detected on the DC line. When HIGH, detection of interference switches
pull down
the operating frequency between F0 and F1. If at the new frequency, no
reception occurred for 2 sec, the operating frequency is switched back.
For designs with a single channel this pin should be tied to ground.
