The content of the registers that are loaded at boot should not be changed. They contain the
factory calibration values. Their content is automatically restored when the device is
powered-up.
Register description
The device contains a set of registers which are used to control its behavior and to retrieve
acceleration data. The registers address, made of 7 bits, is used to identify them and to
write the data through serial interface.
WHO_AM_I (0Fh)
