Table 77. CTRL10_C register description

TIMER_EN

Enable timestamp count. The count is saved in TIMESTAMP0_REG (40h),

TIMESTAMP1_REG (41h) and TIMESTAMP2_REG (42h). Default: 0

(0: timestamp count disabled; 1: timestamp count enabled)

TILT_EN

Enable tilt calculation.(1)

1. This is effective if the FUNC_EN bit is set to '1'.

FUNC_EN

Enable embedded functionalities (tilt, sensor hub and ironing). Default value: 0

(0: disable functionalities of embedded functions and accelerometer filters;

1: enable functionalities of embedded functions and accelerometer filters)

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;

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

_MODE

I2C interface pass-through. Default value: 0

(0: pass-through disabled; 1: pass-through enabled)

IRON_EN

Enable hard-iron correction algorithm for magnetometer(1). Default value: 0

(0:hard-iron correction algorithm disabled;

1: hard-iron correction algorithm enabled)

1. This is effective if the FUNC_EN bit is set to '1'.

MASTER_ON

Sensor hub I2C master enable(1). Default: 0

(0: master I2C of sensor hub disabled; 1: master I2C of sensor hub enabled)
