TMG3992 − Detailed Description

and data collection rate. If wait is enabled, WEN=1, the delay is

adjustable from 2.78ms to 8.54s, as set by the value in the

WTIME register and WLONG control bit.

Sleep After Interrupt Operation

After all the enabled engines/operational states have executed,

causing a hardware interrupt, the state machine returns to

either IDLE or SLEEP, as selected by the Sleep After Interrupt bit,

SAI. SLEEP is entered when two conditions are met: SAI = 1, and

the INT pin has been asserted. Entering SLEEP does not

automatically change any of the register settings (E.g. PON bit

is still high, but the normal operational state is over-ridden by

SLEEP state). SLEEP state is terminated by an I2C clear of the INT

pin or if SAI bit is cleared.

Proximity Operation

The Proximity detection feature provides object detection

measurement by photodiode detection of reflected IR energy

sourced by the integrated LED. The following registers and

control bits govern proximity operation and the operational

flow is depicted inFigure 30.
