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)
