—

All enabled functions still run in SLEEP mode at the SLEEP ODR.

Only the functions that have been selected for WAKE from SLEEP will actually WAKE the device (as configured in

—

Note that the FIFO does not WAKE the device.

—

The Auto-WAKE/SLEEP interrupt does not affect the WAKE/SLEEP, nor does the data ready interrupt.

—

When set to 1, the FIFO gate (bit 7 in Register 0x2C) will hold the last data in the FIFO, before transitioning to a

different ODR. After the buffer is flushed, it will accept new sample data at the current ODR. See Register 0x2C for

the WAKE-from-SLEEP interrupt enable bit definitions.

•

MMA8652FC has 4 functions that can be used to keep the sensor from falling asleep: Transient, Orientation, Tap and Motion/

Freefall.

•

Auto-SLEEP bit:

—

If the Auto-SLEEP bit is disabled, then the device can only toggle between STANDBY and WAKE mode.

—

If Auto-SLEEP interrupt is enabled, then transitioning from ACTIVE mode to Auto-SLEEP mode (or vice versa)

generates an interrupt.
