Write 0xC0 to Control Register 1 (CNTL1) to set the accelerometer in operating mode, high
performance (full power), and G-range to ±2g.

Monitor the physical interrupt INT1 of the accelerometer, if the acceleration input profile
satisfies the criteria previously established for the 0.5g free-fall detect threshold level in both
positive and negative directions of the X, Y, Z axis for more than 0.320 second, then there
should be a positive latched interrupt present. Free-fall events will now be reflected in bit 4 of
STATUS_REG (INT bit), and bit 7 of INS2 registers,
-
Read Interrupt Latch Release (INT_REL) register to unlatch (clear) the output interrupt
created by the free-fall detection function. The read value is dummy.
