into 4-digit hexadecimal V
adj
’ (signed short type),
and assume higher-order 1byte as D
50
and lower-order 1byte
as D
51
.
If V
adj
is a positive value: Convert as it is.
e.g.: When V
adj
= 20
V
adj
’ = 0014
D

= 00, D
51
= 14
If V
adj
is a negative value: Add 65536 and then convert it.
e.g.: When V
adj
= –20
(–20) + 65536 = 65516
V

’ = FFEC
D
