The device contains a set of registers which are used to control its behavior and to retrieve

acceleration and magnetic data. The register address, consisting of 7 bits, is used to identify

them and to write the data through the serial interface.

8.1

TEMP_OUT_L (05h), TEMP_OUT_H (06h)

Temperature sensor data. Temperature data is stored as two’s complement data in 12-bit

format, right-justified.

Refer to Section 4.2 for details on how to enable and read the temperature sensor output

data.

Table 18. STATUS_M register description

ZYXMOR/

Tempor

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

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

Temperature data overrun if T_ONLY bit in CTRL7 (26h) is set to ‘1’. Default value: 0.

ZMOR

Z-axis data overrun. Default value: 0

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

data)

YMOR

Y-axis data overrun. Default value: 0

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

data)

XMOR

X-axis data overrun. Default value: 0

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

data)

ZYXMDA/

Tempda

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

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

Temperature new data available if the T_ONLY bit in CTRL7 (26h) is set to ‘1’.

ZMDA

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)

YMDA

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)

XMDA

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)
