(Note 1) Cannot be specified when the operation unit is 16-bit integer (SS, US).
(Note 2) Only 16-bit devices, 32-bit devices, and integer constants can be modified. (Real number constants,
and character constants cannot be specified.)
(Note 3) Index register (I0 to IE)
(Note 4) Can be specified only when the operation unit is signed integer (SS, SL).
(Note 5) Can be specified only when the operation unit is unsigned integer (US, UL).
(Note 6) Can be specified only when the operation unit is integer (US, SS, UL, SL).
(Note 7) Can be specified only when the operation unit is a single-precision floating point real number (SF).
(Note 8) Can be specified only when the operation unit is a double-precision floating point real number (DF).
