Conversion Instructions Section 3-12
Description BCD(024) converts the binary data in S to BCD data and writes the result to
R.
Flags
Precautions The content of S must not exceed 270F (9999 decimal).
Example The following diagram shows an example BCD-to-binary conversion.
In this example, N words of binary data is converted to BCD data.
If N = 3, the three words of binary starting from D00010 will be converted to
binary data one word at a time when CIO 00000 turns ON. The resulting BCD
data will be stored starting from D00100.
