Keith,
If I'm understanding your question correctly, the answer is yes. ATR is set
up to allow a GPIO pin to vary its state based on whether a channel of the
radio is transmitting or receiving. You can set this per-pin and
per-channel. You can also use GPIO without tying it to ATR at all. Here's a
GPIO example that goes through setup and demonstrates these options:

Best,
