OPERAND-SIZE AND ADDRESS-SIZE ATTRIBUTES
When the processor is executing in protected mode, every code segment has a default operandsize attribute and address-size attribute. These attributes are selected with the D (default size) flag in the segment descriptor for the code segment (see Chapter 3, Protected-Mode Memory Management, in the Intel Architecture Software Developer s Manual, Volume 3). When the D flag is set, the 32-bit operand-size and address-size attributes are selected; when the flag is clear, the 16-bit size attributes are selected. When the processor is executing in real-address mode, virtual-8086 mode, or SMM, the default operand-size and address-size attributes are always 16 bits.
The operand-size attribute selects the sizes of operands that instructions operate on. When the 16-bit operand-size attribute is in force, operands can generally be either 8 bits or 16 bits, and when the 32-bit operand-size attribute is in force, operands can generally be 8 bits or 32 bits.
