Register description
LSM303D
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.
8.2
STATUS_M (07h)
ZYXMOR/ Tempor

ZMOR YMOR XMOR ZYXMDA / Tempda
ZMDA YMDA XMDA
Table 18. STATUS_M register description
ZYXMOR/ Magnetic X, Y and Z-axis and temperature data overrun. Default value: 0
Tempor (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/ X, Y and Z-axis and temperature new data available. Default value: 0
Tempda (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)
