Negative Flag

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 conversion, 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: negative, OFF: positive). Use

STC(040) and CLC(041) to turn the Carry Flag ON and OFF.

The following equations are used for the conversion.

R = Binary conversion of X

Note: 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.

• The source value in S is treated as an absolute BCD value and the sign is indicated by the Carry

Flag. The source value can thus be between –9999 and 9999.

• If the result is less than the minimum conversion value, the minimum conversion value will be output

as the result. If the result is greater than the maximum conversion value, the maximum conversion

value will be output.

• ON if the contents of S is not BCD.

• ON if the contents of C+1 ( X) is not between 0001 and 9999 BCD.

• OFF in all other cases.

• ON if the result is 0.

• OFF in all other cases.

• ON when the MSB of the R (the result) is 1.

• OFF in all other cases.
