Register (0x0A) contains the status of the new data interrupt.
Register (0x0B) contains the sign and triggering axis information for the tap and slope
interrupts. Here tap interrupt comprises both single and double tap interrupt.
Register (0x0C) contains the flat and orientation status, and the sign and triggering axis
information for the high-g interrupt. Registers (0x0D) and (0x0E) are reserved.
Registers (0x0D) and (0x0E) are reserved.
