The capacitance (Ce +Ci) needed at each TOSC pin can be calculated by using:
where:
Crystals specifying load capacitance (CL) higher than 8.0 pF, require external capacitors applied
as described in
When this oscillator is selected, start-up times are determined by the SUT Fuses and CKSEL0
as shown in
Table 6-9.

– Ce - is optional external capacitors as described in Figure 8-2 on page29
– Ci - is the pin capacitance in table 8-8 on page 33
– CL - is the load capacitance for a 32.768 kHz crystal specified by the crystal vendor
– CS - is the total stray capacitance for one TOSC pin.
1. These options should only be used if frequency stability at start-up is not important for the
application.
