The XE1205 contains two SPI-compatible serial interfaces, one to send and read the chip configuration, the other to send
and receive data in buffered mode. Both interfaces are configured in slave mode and share the same pins MISO (Master
In Slave Out), MOSI (Master Out Slave In), SCK (Serial Clock). Two additional pins are required to select the SPI
interface: NSS_CONFIG to change or read the transceiver configuration, and NSS_DATA to send or read data.
Figure 1 shows the connections between the transceiver and a microcontroller when buffered mode is used.
For more information about the serial interface, please refer to the XE1205 datasheet chapter: Serial Interface definition
and principle of operation. You can find this at
