Function
When the input is ON, this instruction converts the 4 digits of BCD data of
A
into binary, and stores in
B
. If any digit of
A
contains non-BCD code (other than H0 through H9), the conversion is not executed
and the instruction error flag (ERF = S051) is set to ON.

Example
When R017 is ON, the BCD data of RW28 is converted into binary data, and the result is stored in
D0127.
For example, if RW28 is H1234, the binary data 1234 is stored in D0127.
RW28 BCD to Binary D0127
H1234 1234
Note
·
If any digit of operand
A
contains non-BCD data, e.g. H13A6, the conversion is not executed and
the instruction error flag (ERF = S051) is set to ON.
