BEHAVIORS AND RESTRICTIONS:
• Specifying an index value with Operand 1 direct results in an instruction encoding exception.
• If the immediate data is smaller than the move size, then the value is sign-extended to the
width of the move.
• If Operand 1 is a register, then the value is stored to the register with bits beyond the move
size cleared.
