least 22pF. By programming the CKOPT Fuse, the user can enable an internal 36pF capacitor
between XTAL1 and GND, thereby removing the need for an external capacitor.
Figure 12. External RC Configuration
The Oscillator can operate in four different modes, each optimized for a specific frequency
range. The operating mode is selected by the fuses CKSEL3..0 as shown in
Table 7. External RC Oscillator Operating Modes
When this Oscillator is selected, start-up times are determined by the SUT Fuses as shown in
Table
