Data Control Instructions
Section 3-18
Description
SCL2(486) is used to convert the signed binary data contained in the source
word S into signed BCD data (the BCD data contains the absolute value and
the Carry Flag shows the sign) and place the result in the result word R
according to the linear function defined by the slope (
∆
X,
∆
Y) and an offset.
The address of the first word containing
∆
X,
∆
Y, and the offset is specified for
the first parameter word P1. The sign of the result is indicated by the status of
the Carry Flag (ON: negative, OFF: positive).
The following equations are used for the conversion.
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.
The result in R will be the absolute BCD conversion value and the sign will be
indicated by the Carry Flag. The result can thus be between –9999 and 9999.
If the result is less than –9999, –9999 will be output as the result. If the result
is greater than 9999, 9999 will be output.
