3 Basic System Operation

3.5.4 Defining Function I/O

3-26

2. Fig. 3.8 shows an example of the I/O definitions of a function.

Fig. 3.8 Graphic Representation of a Function 2 (Example)

3. I/O signal addresses are automatically allocated from the highest signal on the graphic

representation. For the example given in Fig. 3.8, the allocation of each I/O register will
be as shown in Table 3.10.

Note: XW00000 and YW00000 of the X and Y registers are used for bit

data.

4. The function I/O registers shown in Fig. 3.8 are allocated automatically. The external

framework of the function is completed at this stage.
