Table 454. MASTER_CONFIG register description

RST_MASTER_REGS

Reset Master logic and output registers. Must be set to ‘1’ and then set it to ‘0’. Default value: 0

WRITE_ONCE

Slave 0 write operation is performed only at the first sensor hub cycle.

Default value: 0

(0: write operation for each sensor hub cycle;

1: write operation only for the first sensor hub cycle)

START_CONFIG

Sensor hub trigger signal selection. Default value: 0

(0: sensor hub trigger signal is the accelerometer/gyro data-ready;

1: sensor hub trigger signal external from INT2 pin)

PASS_THROUGH_MODE

I²C interface pass-through. Default value: 0

(0: pass-through disabled;

1: pass-through enabled, main I²C line is short-circuited with the auxiliary line)

SHUB_PU_EN

Master I²C pull-up enable. Default value: 0

(0: internal pull-up on auxiliary I²C line disabled;

1: internal pull-up on auxiliary I²C line enabled)

MASTER_ON

Sensor hub I2C master enable. Default: 0

(0: master I2C of sensor hub disabled; 1: master I2C of sensor hub enabled)

AUX_SENS_ON[1:0]

Number of external sensors to be read by the sensor hub.

(00: one sensor (default);

01: two sensors;

10: three sensors;

11: four sensors)
