Operation processing
• These functions convert the data for bits specified by (n) starting from the bit array element input to (s) to ANY 16 type data
and output from (d).
• "0" is set to output bits beyond the specified number of bits.

Operation result
1.
Function without EN/ENO
The operation processing is executed. The operation output value is output from (d).
2.
Function with EN/ENO
The following table lists the execution conditions and operation results.
*1 When FALSE is output from ENO, data output from (d) is undefined. In that case, modify a program so that the data output from (d) is
not used.
Operation error
There is no operation error.
