Low-frequency Crystal Oscillator
Atmel ATtiny24/44/84 [Preliminary]
Table 7-4.
Notes:
To use a 32.768kHz watch crystal as the clock source for the device, the low-frequency crystal
oscillator must be selected by setting CKSEL fuses to “0110”. The crystal should be connected
as shown in
lator operation and how to choose appropriate values for C1 and C2.
When this oscillator is selected, start-up times are determined by the SUT fuses as shown in
Table
Table 7-5.
