7.5.2 Special registers
Special registers are internal registers whose applications are fixed in the
Motion controller. For this reason, it is not possible to use these registers in
Motion SFC programs in the same way that normal registers are used.
However, data can be written as needed in order to control the Motion
controller.
Data stored in the special registers are stored as BIN values if no special
designation has been made to the contrary.
Explanation of headings used in the table on the next page.
