Load Half Word Algebraic
if rA = 0 then b ← 0
else b ← (rA)
EA ← b + EXTS(d)
rD ← EXTS(MEM(EA, 2))
EA is the sum (rA|0) + d. The half word in memory addressed by
EA is loaded into the low-order 16 bits of rD. The remaining bits
in rD are filled with a copy of the most-significant bit of the loaded
half word.
