SCL3(487) is used to convert the signed BCD data (the BCD data contains
the absolute value and the Carry Flag shows the sign) contained in the source
word S into signed binary data and place the result in the result word R
according to the linear function defined by the slope ( X, Y) and an offset.
The maximum and minimum conversion values are also specified. The
address of the first word containing X, Y, the offset, the maximum conver-
sion, and the minimum conversion is specified for the first parameter word P1.
The sign of the result is indicated by the status of the Carry Flag (ON: nega-
tive, OFF: positive). Use STC(040) and CLC(041) to turn the Carry Flag ON
and OFF.
The following equations are used for the conversion.
∆Y
R = Binary conversion of ∆X x ((Binary conversion of S)+(Offset))
The slope of the line is ∆Y/∆X.
The offset and slope can be a positive value, 0, or a negative value. Using a
negative slope enables reverse scaling.
The result will be rounded to the nearest integer.
