FUNCTIONAL INSTRUCTIONS
In preparing a sequence program, some functions such as the function for
controlling rotation via the shorter path, are difficult to program with
basic instructions, which perform only one–bit logical operations.
Therefore, functional instructions are available to facilitate
programming. See Table 5 (a).
