Registers description

LSM303DLH

34/47

Doc ID 16941 Rev 1

This register sets the acceleration value taken as a reference for the high-pass filter output.

When the filter is turned on (at least one FDS, HPen2, or HPen1 bit is equal to ‘1’) and HPM

bits are set to “01”, filter out is generated taking this value as a reference.

9.1.8

STATUS_REG_A(27h)

9.1.9

OUT_X_L_A (28h), OUT_X_H_A (29h)

X-axis acceleration data. The value is expressed as two’s complement.

9.1.10

OUT_Y_L_A (2Ah), OUT_Y_H_A (2Bh)

Y-axis acceleration data. The value is expressed as two’s complement.

9.1.11

OUT_Z_L_A (2Ch), OUT_Z_H_A (2Dh)

Z-axis acceleration data. The value is expressed as two’s complement.

STATUS_REG_A description

ZYXOR

X, Y and Z axis data overrun. Default value: 0

(0: no overrun has occurred;

1: new data has overwritten the previous one before it was read)

ZOR

Z axis data overrun. Default value: 0

(0: no overrun has occurred;

1: new data for the Z-axis has overwritten the previous one)

YOR

Y axis data overrun. Default value: 0

(0: no overrun has occurred;

1: new data for the Y-axis has overwritten the previous one)

XOR

X axis data overrun. Default value: 0

(0: no overrun has occurred;

1: new data for the X-axis has overwritten the previous one)

ZYXDA

X, Y and Z axis new data available. Default value: 0

(0: a new set of data is not yet available; 1: a new set of data is available)

ZDA

Z axis new data available. Default value: 0

(0: new data for the Z-axis is not yet available;

1: new data for the Z-axis is available)

YDA

Y axis new data available. Default value: 0

(0: new data for the Y-axis is not yet available;

1: new data for the Y-axis is available)

XDA

X axis new data available. Default value: 0

(0: new data for the X-axis is not yet available;

1: new data for the X-axis is available)
