Low Frequency Crystal Oscillator
Table 6-9.
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
53. When this Oscillator is selected, start-up times are determined by the SUT Fuses and
CKSEL0 as shown in
Table 6-10.
