3. The crystal should be fundamental mode, parallel resonant. Do not use third overtone. For exact tuning when using a crystal, capacitors
should be connected from pins X1/CLK to GND and X2 to GND. The value of these capacitors is given by the following equation, where
CL is the specified crystal load capacitance: Crystal capacitance (pF) = (CL 5) X 2. So, for a crystal with 16 pF load capacitance, use
two 22 pF capacitors.

4. The crystal should be fundamental mode, parallel resonant. Do not use third overtone. For exact tuning when using a crystal, capacitors
should be connected from pins X1/CLK to GND and X2 to GND. The value of these capacitors is given by the following equation, where
CL is the specified crystal load capacitance: Crystal capacitance (pF) = (CL 12) X 2. So, for a crystal with 16 pF load capacitance, use
two 8 pF capacitors.
