CTRL_REG3 [Interrupt CTRL register] (22h)
7.5
HP_FILTER_RESET (23h)
Dummy register. Reading at this address zeroes instantaneously the content of the internal
high pass-filter. If the high pass filter is enabled all three axes are instantaneously set to 0g.
This allows to overcome the settling time of the high pass filter.
