(RT) EXTS(MS(EA,2))
An effective address (EA) is formed by adding a displacement to a base address. The displacement is
obtained by sign-extending the 16-bit D field to 32 bits. The base address is 0 if the RA field is 0 and is the
contents of register RA otherwise.
The halfword at the EA is sign-extended to 32 bits and placed into register RT.
