BFI – indicates buffer full interrupt. Automatically cleared when buffer is read.
BFI = 0 – Buffer is not full
BFI = 1 – Buffer is full
WMI – Watermark interrupt, bit is set to one when FIFO has filled up to the value stored in the
sample bits. This bit is automatically cleared when FIFO/FILO is read and the content
returns to a value below the value stored in the sample bits.
WMI = 0 – Buffer watermark has not been exceeded
WMI = 1 – Buffer watermark has been exceeded
DRDY – indicates that new acceleration data (0x06h to 0x0Bh) is available. This bit is cleared
when acceleration data is read or the interrupt release register INT_REL is read.
DRDY = 0 - new acceleration data not available
DRDY = 1 - new acceleration data available
TDTS(1,0) – status of tap/double tap, bit is released when interrupt release register INT_REL is
read.

WUFS – Status of Wake up. This bit is cleared when the interrupt release register INT_REL is
read.
WUFS = 1 – Motion has activated the interrupt
WUFS = 0 – No motion
TPS – Tilt Position status. This bit is cleared when the interrupt release register INT_REL is
read.
TPS = 0 – Position not changed
TPS = 1 – Position changed
