Conversion Instructions
Section 3-12
Description
BCDL(059) converts the 8-digit hexadecimal (32-bit binary) data in S and S+1
to 8-digit BCD data and writes the result to R and R+1.
Flags
Precautions
The content of S+1 and S must not exceed 05F5 E0FF (9999 9999 decimal).
Examples
The following diagram shows an example of 8-digit BCD-to-binary conversion.
When CIO 000000 is ON in the following example, the hexadecimal value in
CIO 0011 and CIO 0010 is converted to a BCD value and stored in D00200
and D00201.
