/**
 * @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.
