Note: High-Z means high impedance condition, with the state of the INTx pin defined by

the external pull-up or pull-down resistor.

Description

VECM_EN

Vector Magnitude calculation enable:

0 (default): 12-bit vector magnitude result is not calculated on every ODR cycle. The VECM_LSB and

VECM_MSB registers are not included in auto-increment address range.

1: 12-bit vector magnitude result is calculated on every ODR cycle. The VECM_LSB and VECM_MSB

registers are included in auto-increment address range.

Note: The vector magnitude result may also be used as an input to the SDCD function when SDCD_

CONFIG2[MODE] = 1.

X_DIS

X-axis auto-increment disable:

0 (default): X-axis measurement is included in the auto-increment address range for both buffered

and non-buffered modes (default).

1: X-axis measurement is excluded from the auto-increment address range.

Y_DIS

Y-axis auto-increment disable:

0 (default): Y-axis measurement is included in the auto-increment address range for both buffered

and non-buffered modes (default).

1: Y-axis measurement is excluded from the auto-increment address range.

Z_DIS

Z-axis auto-increment disable:

0 (default): Z-axis measurement is included in the auto-increment address range for both buffered

and non-buffered modes (default).

1: Z-axis measurement is excluded from the auto-increment address range.
