Crystals specifying load capacitance (CL) higher than 6.5 pF, require external capacitors applied
as described in
To find suitable load capacitance for a 32.768 kHz crysal, please consult the crystal datasheet.
The Low-frequency Crystal Oscillator must be selected by setting the CKSEL Fuses to “0110” or
“0111”, as shown in
Table
