WAKE_UP_SRC (1Bh)

Wake up interrupt source register (r).

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

_MODE

I2C interface pass-through. Default value: 0

(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'.

Wakeup event detection status on Z-axis. Default value: 0

(0: wakeup event on Z-axis not detected; 1: wakeup event on Z-axis detected)
