TMG49037 − Register Description

Enable Register (ENABLE 0x80)

Enable has fields that power on the device and enable the

functions. Before enabling any functions, all of the bits

associated with each function must be set. Changing control

Reserved.

GEN

Gesture Enable. When asserted, the gesture state machine can be activated

by setting GMODE = 1 or when a proximity value is above the gesture entry

threshold.

PIEN

Proximity Interrupt Enable. When asserted permits proximity interrupts to

be generated, subject to the proximity thresholds and persistence filter.

AIEN

ALS Interrupt Enable. When asserted permits ALS interrupts to be

generated, subject to the ALS thresholds and persistence filter.

WEN

Wait Enable. This bit activates the wait feature. Writing a 1 activates the wait

timer. Writing a 0 disables the wait timer.

PEN

Proximity Enable. This bit activates the proximity function. Writing a 1

enables proximity. Writing a 0 disables proximity.

AEN

ALS Enable. This bit activates the ALS/Color functionality. Writing a 1

enables ALS/Color. Writing a 0 disables ALS/Color.

PON

Power ON. This bit activates the internal oscillator to permit the timers and

ADC channels to operate. Writing a 1 activates the oscillator. Writing a 0

disables the oscillator and clears, PEN, and AEN. Only set this bit after all

other registers have been initialized by the host.
