15 bits corresponds to 14 bits + sign and 14 bits corresponds to 13 bits + sign. After angular calculation, this corresponds to
The mismatch between X and Z (Y and Z) is end-user programmable through the 2 parameters k
To evaluate the error affecting the computed angle i.e. “ATAN” function (See section 6), it is important to take into account the
