Table 39. INT_THS_H_REG register description

These registers set the threshold value for the output to generate the interrupt (INT bit in

INT_SOURCE_REG (64h)). This threshold is common to all three (axes) output values and

is unsigned unipolar. The threshold value is correlated to the current gain and it is unsigned

because the threshold is considered as an absolute value, but crossing the threshold is

detected for both positive and negative sides.

STATUS_REG (67h)

The status register is an 8-bit read-only register. This register is used to indicate device

status.

OUTX_L_REG, OUTX_H_REG (68h - 69h)

The data output X registers are two 8-bit registers, data output X MSB register (69h) and

output X LSB register (68h).

The output data represents the raw magnetic data only if OFFSET_X_REG is equal to zero,

otherwise hard-iron calibration is included.

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