Examples of LHL coding:
Example 1: LHL = 33h = 001100 11b
LHL(7:3) = 1100b = 12d
LHL(1:0) = 11b = 3d
This leads to:
Mantissa (57 - THEADER)=12d
Fraction (57 - THEADER) = 3/4 = 0.75
Therefore:
(57 - THEADER) = 12.75d and THEADER = 44.25d
Example 2:
57 - THEADER = 36.21d
LHL(1:0) = rounded(4*0.21d) = 1d
LHL(7:2) = Mantissa (36.21d) = 36d = 24h
Therefore LHL(7:0) = 10010001 = 91h
Example 3:
57 - THEADER = 36.90d
LHL(1:0) = rounded(4*0.90d) = 4d
The carry must be propagated to the matissa:
LHL(7:2) = Mantissa (36.90d) + 1 = 37d
Therefore LHL(7:0) = 10110000 = A0h
