TMG3992 − Register Description

Configuration Register AF (CONFIG_AF),

Gesture Mode

This register indicates the operational condition of the gesture

state machine.

Figure 85:

Configuration Register AF

Note(s):

1. If GINT (irrespective of GVALID) remains set after the FIFO has been read GFLVL times, this indicates that new data has been added

to FIFO during the last FIFO read.

Clear Interrupt Registers (0xE3, 0xE7)

Interrupts are cleared by read or write access to the appropriate

Reserved.

GFOV

Gesture FIFO Overflow. A setting of 1 indicates that the FIFO has filled to

capacity and that new gesture detector data has been lost.

GVALID

Gesture Valid. GVALID bit is set when GFLVL becomes greater than GFIFOTH

(i.e. FIFO has enough data to set GINT). GVALID is reset when

GMODE = 0 and the GFLVL=0 (i.e. All FIFO data has been read).
