x86 address/operand 16/32 bit setting 17.1.1 Default Segment AttributeFor programs executed in protected mode, the D-bit in executable-segment descriptors determines the default attribute for both address size and operand size. These default attributes apply to the execution of all instructions in the segment. A value of zero in the D-bit sets the default address size and operand size to 16 bits; a value of one, to 32 bits.Programs .. 더보기 이전 1 ··· 411 412 413 414 415 416 417 ··· 423 다음
