Atmel ATtiny24/44/84 [Preliminary]
Figure 7-3.
When this clock source is selected, start-up times are determined by the SUT Fuses as shown
in
Table 7-8.
When applying an external clock, sudden changes in the applied clock frequency must be
avoided to ensure stable operation of the MCU. A variation in frequency of more than 2% from
one clock cycle to the next can lead to unpredictable behavior. It is required to ensure that the
MCU is kept in reset during such changes in the clock frequency.
Note that the system clock prescaler can be used to implement run-time changes of the inter-
nal clock frequency while still ensuring stable operation. See
