Low Frequency Crystal Oscillator
Table 9-6.
Notes:
The device can utilize a 32.768 kHz watch crystal as clock source by a dedicated Low Fre-
quency Crystal Oscillator. The crystal should be connected as shown in
When this Oscillator is selected, start-up times are determined by the SUT Fuses and CKSEL0
as shown in
The Low-Frequency Crystal Oscillator provides an internal load capacitance, see
each XTAL/TOSC pin.
