7.1.3
Flash Clock – clk
FLASH
The Flash clock controls operation of the Flash interface. The Flash clock is usually active simul-
taneously with the CPU clock.
7.1.4
PLL Clock – clk
PLL
The PLL clock allows the PSC modules to be clocked directly from a 64/32 MHz clock. A 16 MHz
clock is also derived for the CPU.
7.1.5
ADC Clock – clk
ADC
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.
7.2
Clock Sources
The device has the following clock source options, selectable by Flash Fuse bits as illustrated
Table 7-1. The clock from the selected source is input to the AVR clock generator, and routed to
the appropriate modules.
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 Table 7-2. The
Table 7-1.
