The Clock Generation Unit can generate the system clock signal
from a number of external or internal clock sources:
•
•
•
•
The programmable on-chip PLL with multiple prescalers generates a clock signal for
maximum system performance from standard crystals, a clock input signal, or from the
on-chip clock source. See also
The Oscillator Watchdog (OWD) generates an interrupt if the crystal oscillator frequency
falls below a certain limit or stops completely. In this case, the system can be supplied
with an emergency clock to enable operation even after an external clock failure.
All available clock signals can be output on one of two selectable pins.
