Ce - is optional external capacitors as described in
Ci - is is the pin capacitance in
CL - is the load capacitance for a 32.768 kHz crystal specified by the crystal vendor.
C
Crystals specifying load capacitance (CL) higher than the ones given in the
35, require external capacitors applied as described in
Figure 8-3.
Crystals specifying load capacitance (CL) higher than listed in
external capacitors applied as described in
To find suitable load capacitance for a 32.768 kHz crysal, please consult the crystal datasheet.
When this oscillator is selected, start-up times are determined by the SUT Fuses and CKSEL0
as shown in
Table 8-9.
