Converts bit type data input to into double word (signed) type data, and outputs the
operation result from .
When the input value is FALSE, 0 is output in double word (signed) type data.
When the input value is TRUE, 1 is output in double word (signed) type data.
Operation result
(1) Function without EN/ENO
An operation is executed and the operation value is output from .
(2) Function with EN/ENO
The following table shows the executing conditions and operation results.
*1 When FALSE is output from ENO, the data output from is undefined.
In this case, create a program so that the data output from is not used.
