UniteDigit_**
UniteDigit_**
The UniteDigit_** instructions join 4-bit units of data into a bit string.
* If you omit the input parameter, the default value is not applied. A building error will occur.
The UniteDigit_** instructions join 4-bit units from the elements of array to join In[]. It creates a bit string
in joined result Out. (Four bits is one digit.)
Number of digits to join Num specifies the number of array elements to join. First, the lower four bits
from each element from In[0] to In[Num−1] are joined to create a bit string with Num digits. To this, 16#0
is added to the upper digits for the number of digits of Out minus the value of Num. The result is stored
in Out.
The name of the instruction is determined by the data type of Out. For example, if Out is the WORD
data type, the instruction is UniteDigit_WORD.
