LIS3DH: Number of bits in FIFO?

I try to use the lis3dh in FIFO_STREAM mode and HighRes mode. But when I read the values they seem to only be 10bit values.

(I am setting CTRL_REG4 = 0x08, CTRL_REG5=0x40 and ODR=100Hz.)


According to AN3308 16-bits values are stored in the FIFO. In the LIS3DH datasheet, on the front page it says "16-bit data output FIFO". But further down in section 3.6 I read "The LIS3DH contains a 10-bit, 32-level FIFO.".


Has any one managed to get 12-bit values from the FIFO?
