Table 35.
FDS bit enables (FDS=1) or bypass (FDS=0) the high pass filter in the signal chain of the
sensor.
CFS1, CFS0 bits defines the coefficient Hpc to be used to calculate the -3dB cut-off
frequency of the high pass filter:
HP_FILTER_RESET (23h)
Dummy register. Reading at this address zeroes instantaneously the content of the internal
high pass-filter. Read data is not significant.
