START_
CONFIG
Sensor Hub trigger signal selection. Default value: 0
(0: Sensor hub signal is the XL/Gyro data-ready;
1: Sensor hub signal external from INT2 pad.)
PULL_UP_EN
Auxiliary I²C pull-up. Default value: 0
(0: internal pull-up on auxiliary I²C line disabled;
1: internal pull-up on auxiliary I²C line enabled)
PASS_THROUGH I²C interface pass-through. Default value: 0
_MODE
(0: through disabled; 1: through enabled)
IRON_EN
Enable hard-iron correction algorithm for magnetometer⁽²⁾. Default value: 0
(0:hard-iron correction algorithm disabled;
1: hard-iron correction algorithm enabled)
MASTER_ON
Sensor hub I²C master enable⁽²⁾. Default: 0
(0: master I²C of sensor hub disabled; 1: master I²C of sensor hub enabled)
1. If the TIMER_PEDO_FIFO_DRDY bit in FIFO_CTRL2 (07h) is set to 0, the trigger for writing data in FIFO
is XL/Gyro data-ready, otherwise it's the step detection.
2. This is effective if the FUNC_EN bit is set to '1'.
