If the internal CLK is not being used and the external CLK is not 3.5717 MHz, then the filter response would be the same as the
response shown above, but the frequency will change according to the equation:
Using the equation above, an example of the filter response for a 3.5717 MHz XTAL versus a 3.6864 MHz XTAL can be seen in
