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:
