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)

Device identification register.
This register contains the device identifier that for LIS302DLH is set to 32h.
CTRL_REG1 (20h)

PM bits allow to select between power-down and two operating active modes. The device is
in power-down mode when PD bits are set to “000” (default value after boot).
