TMG3992 − Register Description

Configuration Register AA (CONFIG_AA),

Gesture Mode

This register contains settings that govern which gesture

photodiode pair: North-South and/or East-West will be enabled

(have valid data in FIFO) while the gesture state machine is

collecting directional data. Normal mode enables all four

gesture photodiodes and places data into FIFO as expected.

Disabling a photodiode pair, essentially allows the enabled pair

to collect data twice as fast. Data stored in the FIFO for a

disabled pair is not valid. This feature is useful to improve

reliability and accuracy of gesture detection when only

North-South or East-West gestures are expected.
