Data Control Instructions
Section 3-18
In this example, values from 0000 to 00C8 hexadecimal will be converted to
negative values. SCL(194), however, can output only unsigned BCD values
from 0000 to 9999, so 0000 BCD will be output whenever the contents of
D00000 is between 0000 and 00C8 hexadecimal.
Reverse Scaling
Reverse scaling can also be used by setting As < Bs and Ar > Br. The follow-
ing relationship will result.
Reverse scaling can be used, for example, to convert (reverse scale) 1 to 5 V
(0000 to 0FA0 hexadecimal) to 0300 to 0000, respectively, as shown in the fol-
lowing diagram.
