33 INPUT AND OUTPUT DEFINITIONS
36 var1 = 16 bit short signed integer (Word16) whose value falls in
37 the range : 0xffff 8000 <= var1 <= 0x0000 7fff.
39 Local Stores/Buffers/Pointers Needed:
42 Global Stores/Buffers/Pointers Needed:
46 var1 = deposit of var1 into MSWord of 32 bit value (Word32)
48 Pointers and Buffers Modified:
51 Local Stores Modified:
54 Global Stores Modified:
57 ------------------------------------------------------------------------------
60 This function deposits the 16 bit var1 into the 16 MS bits of the 32 bit
61 output. The 16 LS bits of the output are zeroed.
