E.g., to split a uint32 into two uint16 you can use typecast( ):
result = typecast(your_variable,'uint16')
This result will contain the original bit pattern of the input variable.

What about if you have an array for uint32?
It seems typecast places all 16-bits into one array.

Yes. typecast( ) simply re-interprets all of the 32-bit patterns as 16-bit patterns as they appear in memory. So an array input will result in an array output with twice as many elements. Is this not what you want? If you want something different you will have to give a short example of input and desired output.
