8. Precautions for Processing Flow
8.1 About Functions
In this application note, there is a part that is functionalized even in the processing of single line, but this is only
described as a function to clarify the processing for each function. When you actually create a program, you don't
necessarily have to make it functional.
8.2 Settings for Each Channel, FIFO, and Buffer
In this application note, even if processing is required for each channel, FIFO, or buffer, only one processing is
described. When actually creating a program, perform multiple processes as necessary.
8.3 Infinite Loop
To simplify the notation, there are some infinite loops in the processing flow. When actually creating a program, give
each loop a time limit so that it can be exited during overtime. Figure 7-1 shows an example of processing with a loop
time limit.
