I am reading LIS3DSH accelerometer datasheet and I have some questions regarding following text:
2.2 Understanding acceleration data
The measured acceleration data are sent to OUT_X_H, OUT_X_L, OUT_Y_H, OUT_Y_L, OUT_Z_H, and OUT_Z_L registers. These registers contain, respectively, the most significant part and the least significant part of the acceleration signals acting on the X, Y, and Z axes. IEA = 0 IEA = 1 Startup sequence AN3393 14/100 Doc ID 018750 Rev 2 The complete acceleration data for the X (Y, Z) channel is given by the concatenation OUT_X_H & OUT_X_L (OUT_Y_H & OUT_Y_L, OUT_Z_H & OUT_Z_L) and it is expressed in 2’s complement number.
Now, since accelerometer readings are 16bits in size, I know I have to merge the values with AND function, like it states in quote from datasheet?
