Internal Devices
■ Special Data Register (D)
This is a word unit device used for storing numerical data internally in the Touch. Each data register is assigned a
special function. It can also be used as a bit unit device.
Although the device code for the data registers (D0000 to D1999) and special data registers (D8000 to
D8199) is the same ("D"), the device characteristics are different. Special functions are assigned to each
special data register.
Do not change the data of reserved area, otherwise the Touch may not operate correctly.
