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