11.7 Transceiver Crystal Oscillator
8266A-MCU Wireless-12/09
Figure 11-2. External Clock Drive Configuration
When this clock source is selected, start-up times are determined by the SUT Fuses as
shown in
Table 11-7. External Clock Frequency
Table 11-8. Start-up Times for the External Clock Selection
When applying an external clock, it is required to avoid sudden changes in the applied
clock frequency to ensure stable operation of the microcontroller unit (MCU). A variation
in frequency of more than 2% from one clock cycle to the next can lead to unpredictable
behavior. If changes of more than 2% are required, ensure that the MCU is kept in
Reset during the changes.
Note that the System Clock Prescaler can be used to implement run-time changes of
the internal clock frequency while still ensuring stable operation. Refer to section
"System Clock Prescaler" on page 152
The integrated crystal oscillator for the radio transceiver generates a low-jitter 16MHz
clock frequency. See section
the operation of this oscillator. The AVR core and the radio transceiver operate
synchronously on the same clock if this oscillator is selected. If the transceiver crystal
oscillator is selected as AVR core clock, it remains enabled even if the radio transceiver
is in SLEEP mode or its power reduction bit PRTRX24 is set.
