DEN_X
DEN value stored in LSB of X-axis. Default value: 1
(0: DEN not stored in X-axis LSB; 1: DEN stored in X-axis LSB)
DEN_Y
DEN value stored in LSB of Y-axis. Default value: 1
(0: DEN not stored in Y-axis LSB; 1: DEN stored in Y-axis LSB)
DEN_Z
DEN value stored in LSB of Z-axis. Default value: 1
(0: DEN not stored in Z-axis LSB; 1: DEN stored in Z-axis LSB)
DEN_XL_G
DEN stamping sensor selection. Default value: 0
(0: DEN pin info stamped in the gyroscope axis selected by bits [7:5];
1: DEN pin info stamped in the accelerometer axis selected by bits [7:5])
SOFT_EN
Enable soft-iron correction algorithm for magnetometer
(1)
. Default value: 0
(0: soft-iron correction algorithm disabled;
1: soft-iron correction algorithm enabled)
1. This bit is effective if the IRON_EN bit of MASTER_CONFIG (1Ah) and the FUNC_EN bit of CTRL10_C
(19h) are set to 1.
