Table 5. Start-up Times for the Crystal Oscillator Clock Selection
Notes:
To use a 32.768 kHz watch crystal as the clock source for the device, the low-frequency
crystal Oscillator must be selected by setting the CKSEL Fuses to “0110” or “0111”. The
crystal should be connected as shown in Figure 12. When this Oscillator is selected,
start-up times are determined by the SUT Fuses as shown in Table 6 and CKSEL1..0 as
shown in Table 7.
