 # 2 - Integration details
-The driver is platform-independent, you only need to define the two functions for read and write transactions from the sensor hardware bus (ie. SPI or I²C).
+The driver is platform-independent, you only need to define the two functions for read and write transactions from the sensor hardware bus (ie. SPI or I²C). **A few devices integrate an extra bit in the communication protocol in order to enable multi read/write access, this bit must be managed in read and write functions defined by the user.** Please refer to the read and write implementation in the reference examples.
