3 CLOCKS, RESET, INTERRUPTS AND POWER SAVING MODES
3.1 CLOCK SYSTEM
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, or with an external resistor
(R
NET
). In addition, a Low Frequency Auxiliary Os-
cillator (LFAO) can be switched in for security rea-
sons, to reduce power consumption, or to offer the
benefits of a back-up clock system.
The Oscillator Safeguard (OSG) option filters
spikes from the oscillator lines, provides access to
the LFAO to provide a backup oscillator in the
event of main oscillator failure and also automati-
cally limits the internal clock frequency (f
INT
) as a
function of V
DD
, in order to guarantee correct oper-
ation. These functions are illustrated in
Figure 9
,
Figure 10
,
Figure 11
and
Figure 12
.
Figure 8
illustrates various possible oscillator con-
figurations using an external crystal or ceramic res-
onator, an external clock input, an external resistor
(R
NET
), or the lowest cost solution using only the
LFAO. C

an C
L2
should have a capacitance in the
range 12 tST6_CLK1o 22 pF for an oscillator fre-
quency in the 4-8 MHz range.
The internal MCU clock frequency (f
INT
) is divided
by 12 to drive the Timer, the A/D converter and the
Watchdog timer, and by 13 to drive the CPU core,
as may be seen in
Figure 11
.
With an 8MHz oscillator frequency, the fastest ma-
chine cycle is therefore 1.625μs.
A machine cycle is the smallest unit of time needed
to execute any operation (for instance, to increment
the Program Counter). An instruction may require
two, four, or five machine cycles for execution.
3.1.1 Main Oscillator
The oscillator configuration may be specified by se-
lecting the appropriate option. When the CRYSTAL/
RESONATOR option s selected, t must be used with
a quartz crystal, a ceramic resonator or an external
signal provided on he OSCin pin. When he RC NET-
WORK option is selected, the system clock is gen-
erated by an external resistor.
The main oscillator can be turned off (when the
OSG ENABLED option is selected) by setting the
OSCOFF bit of the ADC Control Register. The
Low Frequency Auxiliary Oscillator is automatical-
ly started.
