Table 176. TAP_CFG register description

INTERRUPTS_

ENABLE

Enable basic interrupts (6D/4D, free-fall, wake-up, tap, inactivity). Default value: 0

(0: interrupt disabled; 1: interrupt enabled)

INACT_EN[1:0]

Enable inactivity function. Default value: 00

(00: disabled

01: sets accelerometer ODR to 12.5 Hz (low-power mode), gyro does not change;

10: sets accelerometer ODR to 12.5 Hz (low-power mode), gyro to sleep mode;

11: sets accelerometer ODR to 12.5 Hz (low-power mode), gyro to power-down mode)

SLOPE_

FDS

HPF or SLOPE filter selection on wake-up and Activity/Inactivity functions. Refer to Figure 9.

Default value: 0 (

0: SLOPE filter applied; 1: HPF applied)

TAP_X_EN

Enable X direction in tap recognition. Default value: 0

(0: X direction disabled; 1: X direction enabled)

TAP_Y_EN

Enable Y direction in tap recognition. Default value: 0

(0: Y direction disabled; 1: Y direction enabled)

TAP_Z_EN

Enable Z direction in tap recognition. Default value: 0

(0: Z direction disabled; 1: Z direction enabled)

LIR

Latched Interrupt. Default value: 0

(0: interrupt request not latched; 1: interrupt request latched)
