Figure 12. Crystal Oscillator Connections
The Oscillator can operate in three different modes, each optimized for a specific frequency
range. The operating mode is selected by the fuses CKSEL3..1 as shown in
Table 4. Crystal Oscillator Operating Modes
Notes:
The CKSEL0 Fuse together with the SUT1..0 Fuses select the start-up times as shown in
