This simple logic group divides the received 4-byte value (unsigned) into four 1-byte values.
The four individual values are rounded commercially and output via the outputs "1.byte output", ..., "4.byte output".
Here are the four calculations to extract the individual byte values.
1. Byte) x%256
2. Byte) (x/2^8)%256
3. Byte) (x/2^16)%256
4. Byte) (x/2^24)%256
For the four maths elements, the calculations have been simplified where possible.
