High pass filter setting
Values for REG_CTRL_2 that control the high pass filter. The high pass filter rejects movements that are too slow to be useful. The value used for filtering is expressed as a fraction of the clock rate. To figure out the filter frequency, divide the output data rate by the number at the end of these constants. For example, if you want to detect gestures, you might not be interested in various slow movements (which wouldn't be part of a sharp gesture). If your data rate were 200 Hz, and you don't care about gestures that happen over less than 1 second, then you might want HIGH_PASS_DIV_200, since 200 Hz / 200 = 1 Hz.
