CTRL_REG1. Although the device is in normal mode, CTRL_REG1 content is not
automatically changed to “normal mode” configuration.
HP_FILTER_RESET (25h)
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.
REFERENCE (26h)
Table 33.
Table 34.
This register sets the acceleration value taken as a reference for the high-pass filter output.
When filter is turned on (at least one of FDS, HPen2, or HPen1 bit is equal to ‘1’) and HPM
bits are set to “01”, filter out is generated taking this value as a reference.

X, Y and Z axis data overrun. Default value: 0
(0: no overrun has occurred;
1: new data has overwritten the previous one before it was read)
Z axis data overrun. Default value: 0
(0: no overrun has occurred;
1: a new data for the Z-axis has overwritten the previous one)
Y axis data overrun. Default value: 0
(0: no overrun has occurred;
1: a new data for the Y-axis has overwritten the previous one)
X axis data overrun. Default value: 0
(0: no overrun has occurred;
1: a new data for the X-axis has overwritten the previous one)
Reference value for high-pass filter. Default value: 00h.
