15.31 Sensor Data Change Detection (SDCD) registers

The Sensor Data Change Detection (SDCD) function is an inertial event detection

function available to assist host software algorithms in detecting various inertial events

such as motion/no-motion, high-g/low-g, tap/double tap, and transient acceleration

events.
