-Description:
-
-    Let the effective address (EA) be the register RA.
-
-    The halfword in storage addressed by EA is loaded into RT[48:63].
-    RT[0:47] are filled with a copy of bit 0 of the loaded halfword.
-
-    The sum (RA) + D is placed into register RA.
-
-    If RA=0 or RA=RT, the instruction form is invalid.
