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.
7.1
WHO_AM_I (0Fh)
Device identification register.
This register contains the device identifier that for LIS331DLH is set to 32h.
7.2
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). Table 19
shows all the possible power mode configurations and respective output data rates. Output
data in the low-power modes are computed with low-pass filter cut-off frequency defined by
DR1, DR0 bits.
DR bits, in the normal-mode operation, select the data rate at which acceleration samples
are produced. In low-power mode they define the output data resolution. Table 20 shows all
the possible configuration for DR1 and DR0 bits.
