SAI_ACTIVE

Sleep-After-Interrupt Active. If SAI is set, indicates that the

GTIME

Field

Bits

Description

GTIME

7:0

Gesture Sample Time. Sets the gesture sample rate while in gesture

mode, GMODE. The power on reset value is 0x0A. Gesture data is

collected once for each sample time. There is a minimum GTIME that

must be configured that depends on the GPULSE and PGPULSE_LEN

settings. The maximum GPULSE and PGPULSE_LEN settings for the

default GTIME (0x0A) are GPULSE = 15 (16 pulses) and PGPULSE_LEN = 1

(8μs). Contact technical support for more information.
