5-18 Data Conversion
The conversion instructions convert word data that is in one format into another
format and output the converted data to specified result word(s). Conversions
are available to convert between binary (hexadecimal) and BCD, to 7-segment
display data, to ASCII, and between multiplexed and non-multiplexed data. All of
these instructions change only the content of the words to which converted data
is being moved, i.e., the content of source words is the same before and after
execution of any of the conversion instructions.

Description
When the execution condition is OFF, BIN(23) is not executed. When the execu-
tion condition is ON, BIN(23) converts the BCD content of S into the numerically
equivalent binary bits, and outputs the binary value to R. Only the content of R is
changed; the content of S is left unchanged.

Binary
BIN(23) can be used to convert BCD to binary so that displays on the Program-
ming Console or any other programming device will appear in hexadecimal
rather than decimal. It can also be used to convert to binary to perform binary
arithmetic operations rather than BCD arithmetic operations, e.g., when BCD
and binary values must be added.
Flags
ER:
The content of S is not BCD.
Indirectly addressed DM word is non-existent. (Content of
∗
DM word is
not BCD, or the DM area boundary has been exceeded.)
EQ:
ON when the result is zero.
