By default, the serial control interface is used for configuration. It is also possible to change between the four modes
(sleep, stand-by, receive, transmit) by using the two-bit signal SW(1:0). This option is enabled by setting the bit
MCParam_Select_mode to ‘1’ in the configuration register.
If MCParam_Select_mode is low, the modes are defined by the register through the SPI_CONFIG interface and SW(1:0)
may be used as an output to control, for example, an antenna switch.
For more information about the modes of operation, please refer to the XE1205 Datasheet on the Semtech website
