Function
The ToAryByte instruction separates the value of data to convert In into individual bytes and stores
them in order in conversion results array AryOut[] starting from AryOut[0]. Number of elements in result
Out contains the number of elements stored in AryOut[].
Conversion order Order specifies the order in which to convert the value of In to bytes. The data type of
Order is enumerated type _eBYTE_ORDER. The meaning of the enumerators are as follows:
