1. This bit must be set to 0 for the correct operation of the device.

Table 190. EMB_FUNC_EN_A register description

MLC_BEFORE_FSM_EN(1)

Enables the machine learning core function. When the machine learning core is enabled by

setting this bit to 1, the MLC algorithms are executed before the FSM programs. Default value: 0

(0: machine learning core function disabled;

1: machine learning core function enabled and executed before FSM programs)

SIGN_MOTION_EN

Enables significant motion detection function. Default value: 0

(0: significant motion detection function disabled;

1: significant motion detection function enabled)

TILT_EN

Enables tilt calculation. Default value: 0

(0: tilt algorithm disabled;

1: tilt algorithm enabled)

PEDO_EN

Enables pedometer algorithm. Default value: 0

(0: pedometer algorithm disabled;

1: pedometer algorithm enabled)

SFLP_GAME_EN

Enables sensor fusion low-power algorithm for 6-axis (accelerometer + gyroscope) game

rotation vector. Default value: 0

(0: sensor fusion algorithm for 6-axis accelerometer + gyroscope disabled;

1: sensor fusion algorithm for 6-axis accelerometer + gyroscope enabled)

1. MLC_EN bit in the EMB_FUNC_EN_B (05h) register must be set to 0 when using this bit.
