ADC
The Flash clock controls operation of the Flash interface. The Flash clock is usually active
simultaneously with the CPU clock.
The PLL clock allows the fast peripherals to be clocked directly from a 64/32MHz clock. A
16MHz clock is also derived for the CPU.
The ADC is provided with a dedicated clock domain. This allows halting the CPU and I/O
clocks in order to reduce noise generated by digital circuitry. This gives more accurate ADC
conversion results.
The device has the following clock source options, selectable by Flash Fuse bits as illustrated
Table 5-1. The clock from the selected source is input to the AVR clock generator, and routed
to the appropriate modules.
Table 5-1.
Note:
The various choices for each clocking option is given in the following sections. When the CPU
wakes up from Power-down or Power-save, the selected clock source is used to time the
start-up, ensuring stable Oscillator operation before instruction execution starts. When the
CPU starts from reset, there is an additional delay allowing the power to reach a stable level
before starting normal operation. The Watchdog Oscillator is used for timing this real-time part
of the start-up time. The number of WDT Oscillator cycles used for each time-out is shown in
