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.
Indirect DM/EM
addresses in binary
@ D00000 to @ D32767
@ E00000 to @ E32767
@ En_00000 to @ En_32767
(n = 0 to C)
Indirect DM/EM
addresses in BCD
*D00000 to *D32767
*E00000 to *E32767
*En_00000 to *En_32767
