TMG3992 − Register Description

Configuration Register AB (CONFIG_AB),

Gesture Mode

This register contains settings that govern Gesture interrupts

as well as operation mode control.

Figure 83:

Configuration Register AB

Configuration Register AE (CONFIG_AE),

Gesture Mode

This indicates the number of datasets that are currently

available in the FIFO for read. Reading a complete FIFO dataset

(from address 0xFC to 0xFF) constitutes the reduction of the

GPENTH register by one.

Description

Reserved

7:2

Reserved. Bits must be set to 0.

GIEN

Gesture Interrupt Enable. When asserted, all gesture related interrupts are

unmasked.

GMODE

Gesture Mode. Reading this bit reports if the gesture state machine is actively

running, 1 = Gesture, 0= ALS, Proximity, Color, and Pattern Burst. Writing a 1 to

this bit causes immediate entry in to the gesture state machine (as if GPENTH

had been exceeded). Writing a 0 to this bit causes exit of gesture when current

analog conversion has finished (as if GPEXTH had been exceeded).

Description

GFLVL

7:0

Gesture FIFO Level. This register indicates how many four byte data

points—NSWE are ready for read over I²C. One four-byte dataset is

equivalent to a single count in GFLVL.
