1. This bit must be set to ‘0’ for the correct operation of the device.
DRDY_ON_
INT1
Table 75. MASTER_CONFIG register description
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)
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
MASTER_ON
Enable hard-iron correction algorithm for magnetometer. Default value: 0
(0:hard-iron correction algorithm disabled;
1: hard-iron correction algorithm enabled)
Sensor hub I²C master enable. 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.
