Data Conversion Instructions
Converting binary data to BCD 4-digit data
BCD(P)
These instructions convert the binary data in the device specified by (s) to BCD data, and store the converted data in the
device specified by (d).
Binary data is used in operations in CPU module. Use this instruction to display numeric values on seven-segment display
unit equipped with BCD decoder.
