Conversion Instructions Section 5-19
Example When 00000 is ON, the following diagram encodes IR words 010 and 011 to
the first two digits of HR 10 and then encodes LR 10 and 11 to the last two
digits of HR 10. Although the status of each source word bit is not shown, it is
assumed that the bit with status 1 (ON) shown is the highest bit that is ON in
the word.
5-19-7 7-SEGMENT DECODER – SDEC(78)
Limitations Di must be within the values given below.
All destination words must be in the same data area.
DM 6144 to DM 6655 cannot be used for D.
Description When the execution condition is OFF, SDEC(78) is not executed. When the
execution condition is ON, SDEC(78) converts the designated digit(s) of S into
the equivalent 8-bit, 7-segment display code and places it into the destination
word(s) beginning with D.
