Table 32. CTRL_REG5 register

FAST_READ

BDU

0(1)

1. These bits must be set to ‘0’ for correct functioning of the device

0(1)

Table 33. CTRL_REG5 description

FAST_READ

FAST READ allows reading the high part of DATA OUT only in order to increase

reading efficiency. Default value: 0

(0: FAST_READ disabled; 1: FAST_READ enabled)

BDU

Block data update for magnetic data. Default value: 0

(0: continuous update;

1: output registers not updated until MSb and LSb have been read)

ZYXOR

ZOR

YOR

XOR

ZYXDA

ZDA

YDA

XDA

Table 35. STATUS_REG 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)
