3 CLOCKS, RESET, INTERRUPTS AND POWER SAVING MODES
3.1 CLOCK SYSTEM
3.1.1 Main Oscillator
The MCU features a Main Oscillator which can be
driven by an external clock, or used in conjunction
with an AT-cut parallel resonant crystal or a suita-
ble ceramic resonator.
Figure 8 illustrates various possible oscillator con-
figurations usingan external crystalorceramic res-
onator, an external clock input. C

L2
should
have a capacitance in the range 12 to 22 pF for an
oscillator frequency in the 4-8 MHz range.
The internal MCU clock Frequency (F
INT
) is divid-
ed by 13 to drive the CPU core and by 12 to drive
the A/D converter and the watchdog timer, while
clock used to drive on-chip peripherals depends
on the peripheral as shown in the clock circuit
block diagram.
With an 8MHz oscillator frequency, the fastest
machine cycle is therefore 1.625
μ
s.
A machine cycleis thesmallest unit of time needed
to execute anyoperation (forinstance,to increment
the Program Counter). An instruction may require
two, four, or five machine cycles for execution.
