STATUS_REG description

ZYXOR

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

(0: no overrun has occurred; 1: new data has overwritten the previous data 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 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, 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)
