8.6 (0x09) Status Register 2
This register reports the state of the interrupts. A interrupt flag bit in this register will only
transition if the corresponding interrupt enable is set to ‘1’ in the Interrupt Control Register.
Reading this register will clear any pending interrupts that are waiting for servicing.

INT_WAKE
This interrupt will transition when the accelerometer
automatically moves from SNIFF to CWAKE. Once
cleared, another SNIFF to CWAKE event must take
place to retrigger it.
3
INT_ACQ
This interrupt will transition when a new sample is
acquired. This flag stays high upon the first sample
acquired and will not rearm unless serviced.
4
INT_FIFO_EMPTY
This interrupt will transition when the FIFO is empty.
This flag stays high upon the first empty condition
and will not rearm unless serviced.
5
INT_FIFO_FULL
This interrupt will transition when the FIFO is full.
This flag stays high upon the first empty condition
and will not rearm unless serviced.
6
INT_FIFO_THRESHOLD This interrupt will transition when the FIFO sample
count is equal to or greater than the threshold count.
This flag stays high upon the first threshold condition
and will not rearm unless serviced.
