• Manufacturer Part Number: xe1205
• Description: Low-power, High Link Budget Integrated Uhf Transceiver
• Manufacturer: Semtech Corporation

The XE1205 has several operating modes, configuration parameters and internal status registers that may be accessed
by the microcontroller via the SPI_CONFIG interface.
The switching pins SW(1:0) allows switching between one of the four operating modes (sleep, stand-by, receive,
transmit) when MCParam_Select_mode is high. 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.
