// SADS (Switched Antenna Diversity Selection)
//
// Some WiFi modules have one antenna that mux both BT and Wi-Fi. Antenna diversity allows these devices
// to use one of the 2 possible antennas with the following options:
// 1.Antenna1:
// Wi-Fi and BT are always connected to antenna #1 and switched antenna diversity is disabled.
// 2.Antenna2:
// Wi-Fi and BT are always connected to antenna #2 and switched antenna diversity is disabled.
// 3.Diversity:
// Wi-Fi and BT are connected to either antenna #1 or antenna #2, according to Wi-Fi algorithm
// decision, and switched antenna diversity is enabled.
// 4.Diversity_Antenna1:
// Wi-Fi and BT are connected to either antenna #1 or antenna #2, according to Wi-Fi algorithm
// decision, when initially it is connected to antenna #1 and switched antenna diversity is enabled.
// 5.Diversity_Antenna2:
// Wi-Fi and BT are connected to either antenna #1 or antenna #2, according to Wi-Fi algorithm
// decision, when initially it is connected to antenna #2 and switched antenna diversity is enabled.
