Notes:
1. These options should only be used when not operating close to the maximum frequency of the
device, and only if frequency stability at start-up is not important for the application. These
options are not suitable for crystals.
2. These options are intended for use with ceramic resonators and will ensure frequency stability
at start-up. They can also be used with crystals when not operating close to the maximum fre-
quency of the device, and if frequency stability at start-up is not important for the application.
Note:
1.
The device is shipped with this option selected.

Low frequency crystal oscillator
The device can utilize a 32.768kHz watch crystal as clock source by a dedicated low frequency
crystal oscillator. The crystal should be connected as shown in Figure 7-2 on page 43. When this
Oscillator is selected, start-up times are determined by the SUT Fuses and CKSEL0 as shown in
