Low-frequency Crystal
Oscillator
2467M–AVR–11/04
Table 9. 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-fre-
quency Crystal Oscillator must be selected by setting the CKSEL fuses to “1001”. The
crystal should be connected as shown in Figure 19. By programming the CKOPT fuse,
the user can enable internal capacitors on XTAL1 and XTAL2, thereby removing the
need for external capacitors. The internal capacitors have a nominal value of 36 pF.
When this Oscillator is selected, start-up times are determined by the SUT fuses as
shown in Table 10.
