Register description
27/37
BOOT bit is used to refresh the content of internal registers stored in the flash memory
block. At the device power up the content of the flash memory block is transferred to the
internal registers related to trimming functions to permit a good behavior of the device itself.
If for any reason the content of trimming registers was changed it is sufficient to use this bit
to restore correct values. When BOOT bit is set to ‘1’ the content of internal flash is copied
inside corresponding internal registers and it is used to calibrate the device. These values
are factory trimmed and they are different for every accelerometer. They permit a good
behavior of the device and normally they have not to be changed. At the end of the boot
process the BOOT bit is set again to ‘0’.
HPCF[1:0]. These bits are used to configure high-pass filter cut-off frequency ft which is
given by:
The equation can be simplified to the following approximated equation:
