This instruction multiplies the contents of a 16- or 32-bit register (Rd) by the contents of a 16- or
32-bit register (Rs) or 4-bit immediate value and stores the result (only the lower 16 or 32 bits) in
the 16- or 32-bit register (Rd). (The upper 16 or 32 bits of the result are ignored. The Z or N flag
also changes according to the contents of the lower 16 or 32 bits regardless of the contents of the
upper 16 or 32 bits.) The multiplication is signed.
