There are 2256 special register points of SD0 to SD2255 in the Motion CPU.
Of these, 20 points of the SD200, SD500 to SD506, SD508, SD510 to SD517, SD522,
SD523 and SD803 are used for the positioning control.
The special register list used for the positioning control is shown below.
(Refer to the "Q173DCPU/Q172DCPU Motion controller Programming Manual
(COMMON)" for the applications of special registers except SD200, SD500 to SD506,
SD508, SD510 to SD517, SD522, SD523 and SD803.)
