9.24 WAKE_UP_SRC (1Bh)
Wake up interrupt source register (r).
Table 79. MASTER_CONFIG register description
DRDY_ON_
INT1
Manage the Master DRDY signal on INT1 pad. Default: 0
(0: disable Master DRDY on INT1; 1: enable Master DRDY on INT1)
DATA_VALID_
SEL_FIFO
Selection of FIFO data-valid signal. Default value: 0
(0: data-valid signal used to write data in FIFO is the XL/Gyro data-ready or step
detection
(1)
;
1: data-valid signal used to write data in FIFO is the sensor hub data-ready)
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.
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 I
2
C pull-up. Default value: 0
(0: internal pull-up on auxiliary I
2
C line disabled;
1: internal pull-up on auxiliary I
2
C line enabled)
PASS_THROUGH
_MODE
I
2
C interface pass-through. Default value: 0
(0: pass-through disabled; 1: pass-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)
2. This is effective if the FUNC_EN bit is set to '1'.
MASTER_ON
Sensor hub I
2
C master enable
(2)
. Default: 0
(0: master I
2
C of sensor hub disabled; 1: master I
2
C of sensor hub enabled)

Table 81. WAKE_UP_SRC register description
FF_IA
Free-fall event detection status. Default: 0
(0: free-fall event not detected; 1: free-fall event detected)
SLEEP_
STATE_IA
Sleep event status. Default value: 0
(0: sleep event not detected; 1: sleep event detected)
WU_IA
Wakeup event detection status. Default value: 0
(0: wakeup event not detected; 1: wakeup event detected.)
X_WU
Wakeup event detection status on X-axis. Default value: 0
(0: wakeup event on X-axis not detected; 1: wakeup event on X-axis detected)
Y_WU
Wakeup event detection status on Y-axis. Default value: 0
(0: wakeup event on Y-axis not detected; 1: wakeup event on Y-axis detected)
Z_WU
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)
