TMG49037 − Register Description

Gesture Control Register (GST_CTRL 0xB5)

Figure 53:

Gesture Control Register

Gesture Threshold Registers (0xB6 – 0xB9)

PDATA is compared to GTHR_IN if GEN = 1. If PDATA is greater

than GTHR_IN, the device enters gesture mode (GMODE). Once

in GMODE, the gesture data from each channel is compared to

GTHR_OUT to determine when the device should exit GMODE.

The criteria for exiting GMODE are user-configured. The

proximity persistence filter, PPERS, is not used to determine

gesture state machine entry.

GIEN

Gesture Interrupt Enable. When asserted permits all

gesture-related interrupts to occur. The first gesture interrupt is

subject to GFIFOTHR.

GMODE

Gesture Mode. Reports if the device is in gesture mode. In

gesture mode, GTIME sets the sample rate of the

proximity/gesture state machine, and datasets are added to the

FIFO buffer. Writing 1 to this bit forces the device to enter

gesture mode (as if GTHR_IN has been exceeded). Writing a 0 to

this bit causes exit of gesture when current analog conversion

has finished (as if all gesture data is below GTHR_OUT).
