The size of each block equals to (20*Unit Size+Azimuth Size).
NOTE
Under dual return mode, azimuth angle changes every two blocks. The odd number block is the last return, and the even number block
is the strongest return. If the last and strongest return coincides, the second strongest return will be placed to the even number block.

Represents the current reference angle of the rotor.
Azimuth [15:0]: lower byte Azimuth_L [7:0] is in the front, upper byte Azimuth_H [15:8] is in the back.
Azimuth Angle=[Azimuth_H, Azimuth_L]/100°=Azimuth/100°
