30/51
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.
STATUS_REG (27h)
Table 29.
Table 30.
The content of this register is updated every ODR cycle, regardless of BDU bit value in
CTRL_REG2.
