Description
***********



.. code-block:: none

   This is a representation of generic radio Front-End Module (FEM)
   that has a two-pin control interface (CTX, CRX).

   The CTX control pin is used to enable the Power Amplifier (PA) in
   the transmit path. This is therefore sometimes referred to as
   the "PA pin" in other contexts.

   The CRX control pin is used to enable the Low Noise Amplifier
   (LNA) in the receive path, and is sometimes referred to as
   the "LNA pin" in other contexts.

   Each of these pins is optional, and may be omitted if not present.
   (Though if you do specify a pin, you must also specify its
   corresponding settle-time-us property.)

                wake up the system.

                Wake up capable devices are disabled (interruptions will not wake up
                the system) by default but they can be enabled at runtime if necessary.
