STATUS (27h)

4.20

OUT_X_L (28h), OUT_X_H (29h)

X-axis acceleration data (16-bit), MSB values are in OUT_X_H, LSB values are in

OUT_X_L. The value is expressed in two’s complement.

4.21

OUT_Y_L (2Ah), OUT_Y_H (2Bh)

Y-axis acceleration data (16-bit), MSB values are in OUT_Y_H, LSB values are in

OUT_Y_L. The value is expressed in two’s complement.

4.22

OUT_Z_L (2Ch), OUT_Z_H (2Dh)

Z-axis acceleration data (16-bit), MSB values are in OUT_Z_H, LSB values are in

OUT_Z_L. The value is expressed in two’s complement.

Description

ZYXOR

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

(0: no overrun has occurred; 1: a new set of data has overwritten the previous set)

ZOR

Z-axis data overrun. Default value: 0

(0: no overrun has occurred; 1: new data for the Z-axis has overwritten the previous data)

YOR

Y-axis data overrun. Default value: 0

(0: no overrun has occurred; 1: new data for the Y-axis has overwritten the previous data)

XOR

X-axis data overrun. Default value: 0

(0: no Overrun has occurred; 1: new data for the X-axis has overwritten the previous data)

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 Z-axis is available)

YDA

Y-axis new data available. Default value: 0

(0: a new data for the Y-axis is not yet available; 1: a new data for Y-axis is available)

XDA

X-axis new data available. Default value: 0

(0: a new data for the X-axis is not yet available; 1: a new data for X-axis is available)
