LINK/LOOP

Default Mode.

0x0

Activity and inactivity detection are both enabled, and their interrupts (if

mapped) must be acknowledged by the host processor by reading the

STATUS register. Autosleep is disabled in this mode. Use this mode for free

fall detection applications.

Linked Mode.

Activity and inactivity detection are linked sequentially such that only one

is enabled at a time. Their interrupts (if mapped) must be acknowledged

by the host processor by reading the STATUS register.

Loop Mode.

Activity and inactivity detection are linked sequentially such that only one

is enabled at a time, and their interrupts are internally acknowledged (do

not need to be serviced by the host processor).

To use either linked or looped mode, both ACT_EN (Bit 0) and INACT_EN

(Bit 2) must be set to 1; otherwise, the default mode is used. For additional

information, refer to the Linking Activity and Inactivity Detection section.

INACT_REF

Referenced/Absolute Inactivity Select.

0x0

1 = inactivity detection function operates in referenced mode.

0= inactivity detection function operates in absolute mode.

INACT_EN

Inactivity Enable.

0x0

1 = enables the inactivity (underthreshold) functionality.

ACT_REF

Referenced/Absolute Activity Select.

0x0

1 = activity detection function operates in referenced mode.

0 = activity detection function operates in absolute mode.

ACT_EN

Activity Enable.

0x0

1 = enables the activity (overthreshold) functionality.
