Depending on the crystal a damping series resistor might be necessary
Only valid if full swing Pierce oscillator/external clock mode is selected
These values apply for carefully designed PCB layouts with capacitors that match the crystal/resonator requirements..
Only applies if EXTAL is externally driven
