 **As a Transmitter & Receiver:**
 
-The radio can be used as both a transmitter and receiver. The same pin is used for both rx and tx. In order to make things work the gpio mode and radio mode must be set appropriately. The gpio mode will automatically be set if DIO2 is configured.
+When ``one_wire`` is enabled in :doc:`remote_transmitter </components/remote_transmitter>` the pin will be
+configured in open drain mode. In open drain mode the pin is actively driven low or passively pulled high
+by pull-up. In addition to setting the radio mode the pin output should be set to low before transmit
+and to high before returning to receive.
