1) Calculate Y using following equations. (decimal calculation)
Y = 960 – (19.6 ÷ 18.6) × (SH2 + SH3) ÷ (SH1 × 2) × 1920
+ (1 ÷ 18.6) × (SH2' + SH3') ÷ (SH1' × 2) × 1920
2) Calculate H using following equations. (decimal calculation)
adj
= (Y ÷ 1920) × 3916 ÷ 0.85 ÷ 0.1831

3) Convert H into 4-digit hexadecimal H

and assume higher-order 1byte as D
as D .

If H is a positive value: Convert as it is.
adj
e.g.: When H = 20
adj
H ' = 0014

If H is a negative value: Add 65536 and then convert it.
adj
e.g.: When H = –20
adj
(–20) + 65536 = 65516
H ' = FFEC
