There are 2256 special register points of SD0 to SD2255 in the Motion CPU.
Of these, devices in a Table 3.3 are used for the positioning control.
The special register list used for the positioning control is shown below.
(Refer to the "Q173D(S)CPU/Q172D(S)CPU Motion controller Programming Manual
(COMMON)" for the applications of special registers except below.)
