Low-frequency Crystal Oscillator
Table 4-11.
To use a 32.768kHz watch crystal as the clock source for the device, the low-frequency crystal
oscillator must be selected by setting CKSEL fuses or CSEL field as shown in
page
Crystal Oscillator Application Note for details on oscillator operation and how to choose appro-
priate values for C1 and C2.
The 32.768kHz watch crystal oscillator can be used by the asynchronous timer if the (high-fre-
quency) Crystal Oscillator is not running or if the External Clock is not enabled
