Preliminary Datasheet
8.10 (0x13) Sniff Threshold Control Register
This register sets the threshold the SNIFF logic compares the combined acceleration of X, Y,
and Z to for activity detection.
The mode will transition from SNIFF to CWAKE when the condition below is met, comparing
one sample to the next:

I2C_MODE_EN
0: Device interface is still defined as it was at power-up
but no data will appear in XOUT, YOUT and ZOUT
registers if both this bit and SPI_MODE_EN are set to 0
(default).
1: Disables any SPI communications.
