/**
* @name RF switch controlled by SW
* @brief Controls which RF interface goes to the RP-SMA external antenna
*
* These values configure the required pin to drive the RF antenna switch, to
* either enable the sub-1Ghz RF interface (power-up the CC1200) or the 2.4GHz
* RF interface of the CC2538, both alternatively routed to a RP-SMA connector
* to allow using an external antenna for both cases.
*
* Note it is also possible to enable both RF interfaces at the same time, by
* switching On the sub-1GHz RF interface, and placing an 0Ohm resistor (R19),
* to select between using a ceramic chip antenna (not mounted), or to connect
* and external antenna over a pigtail to the U.Fl connector (not mounted).
*
* RF switch state:
* - LOW: 2.4GHz RF interface on RP-SMA connector, CC1200 powered-off.
* - HIGH: Sub-1GHz RF interface on RP-SMA connector.
