Help¶

Enable implicit initialization of GPIOs responsible for antenna
switching during Radio initialization.
If this feature is not enabled, the Radio initialization procedure will
not initialize GPIOs pins selected to drive antenna switching.
In such case application is responsible for appropriate GPIOs
initialization.
