This command is used to configure DIO2 so that it can be used to control an external RF switch.
When controlling the external RX switch, the pin DIO2 toggles accordingly to the internal state machine. DIO2 is asserted high a few
microseconds before the ramp-up of the PA and is set to zero after the ramp-down of the PA.
