M_OUT_X_MSB (0x33), M_OUT_X_LSB (0x34), M_OUT_Y_MSB (0x35), M_OUT_Y_LSB

(0x36), M_OUT_Z_MSB (0x37), M_OUT_Z_LSB (0x38) registers

X-axis, Y-axis, and Z-axis 16-bit magnetic output data expressed as 2's complement numbers, with a resolution of 0.1

μT/LSB.

9.14.3

CMP_X_MSB (0x39), CMP_X_LSB (0x3A), CMP_Y_MSB (0x3B), CMP_Y_LSB (0x3C),

CMP_Z_MSB (0x3D), CMP_Z_LSB (0x3E) registers

These registers contain the 2’s complement 14-bit decimated acceleration values, and are time aligned with the magnetometer

sample data. The decimation is controlled by the ODR (CTRL_REG1 dr[2:0]) and the magnetometer OSR (M_CTRL_REG1

m_os[2:0]) settings.These registers allow the host application to acquire a complete set of time-aligned magnetic and

acceleration data with the same oversampling ratio applied to each axis. Note that unlike the acceleration data available in the

OUT_X/Y/Z registers located at addresses x1-x6, the data in the CMP_X/Y/Z registers is right justified.

xdr

xdr is set to 1 whenever a new X-axis data acquisition is completed. xdr is cleared anytime the M_OUT_X_MSB register is

read. X-axis new data available:

0: No new X-axis magnetic data is available.

1: New X-axis magnetic data is available
