44 INPUT AND OUTPUT DEFINITIONS
45
46 Inputs:
47    var1 = 16 bit short signed integer (Word16) whose value falls in
48           the range : 0xffff 8000 <= var1 <= 0x0000 7fff.

50 Local Stores/Buffers/Pointers Needed:
51    None
52
53 Global Stores/Buffers/Pointers Needed:
54    None
55
56 Outputs:
57    var1 = deposit of var1 into LSWord of 32 bit value (Word32)
58
59 Pointers and Buffers Modified:
