 Since there is only one I2C bus available in the analog pins 4 (Serial Data Line) and 5 (Serial Clock), and both the accelerometer and the EEPROM need to access it, it was necessary to adapt and control the bus access. To avoid including more hardware to the device, i.e. an I2C multiplexer, it was decided to control the power supply for this modules using the digital pins 10 and 11. This way, both devices can share the I2C bus and use it only when requested. Figure 28 illustrates the power distribution system. Since there is only one I2C bus available in the analog pins 4 (Serial Data Line) and 5 (Serial Clock), and both the accelerometer and the EEPROM need to access it, it was necessary to adapt and control the bus access.
