Latched mode
In latched mode (INT_CONFIG1.latch_int = 1) an asserted interrupt status in INT_STAT(0/1/2) and the
INT pin (the contribution to the ´or´ condition for the INT pin) is cleared by reading the corresponding
status register. If the FIFO filling activation condition still holds true then the interrupt status is not
cleared. Data ready and advanced interrupts' statuses are cleared upon reading INT_STAT register.
Interrupt behavior during power mode switching
When the device leaves normal mode, all internal interrupt status registers are cleared. There are two
exceptions:
- The step counter keeps its state (i.e. the step count) on mode switching. If the mode is switched
to normal with enabled step counter, it continues counting on the previous value. The internal
interrupt status is cleared.
- FIFO interrupts are not cleared by mode switching
