When the shift function is used with the digital clipping function and scaling function, shift-and-add is
performed on the value obtained after digital clipping and scale conversion. Therefore, the range of the digital
operation value is determined as -32768 to +32767.
For a setting example of when the digital clipping function, scaling function, and shift function are used
together, refer to the following.
