7.4 MULTI-OSCILLATOR (MO)
The main clock of the ST7 can be generated by
four different source types coming from the multi-
oscillator block (1 to 16MHz):
■
■
■
Each oscillator is optimized for a given frequency
range in terms of consumption and is selectable
through the option byte. The associated hardware
configurations are shown in
electrical characteristics section for more details.
External Clock Source
In this external clock mode, a clock signal (square,
sinus or triangle) with ~50% duty cycle has to drive
the OSC1 pin while the OSC2 pin is tied to ground.
Note: when the Multi-Oscillator is not used, PB4 is
selected by default as external clock.
Crystal/Ceramic Oscillators
In this mode, with a self-controlled gain feature,
oscillator of any frequency from 1 to 16MHz can be
placed on OSC1 and OSC2 pins. This family of os-
cillators has the advantage of producing a very ac-
curate rate on the main clock of the ST7. In this
mode of the multi-oscillator, the resonator and the
load capacitors have to be placed as close as pos-
sible to the oscillator pins in order to minimize out-
put distortion and start-up stabilization time. The
loading capacitance values must be adjusted ac-
cording to the selected oscillator.
These oscillators are not stopped during the
RESET phase to avoid losing time in the oscillator
start-up phase.
Internal RC Oscillator
In this mode, the tunable 1%RC oscillator is used
as main clock source. The two oscillator pins have
to be tied to ground if dedicately using for oscillator
else can be found as general purpose IO.
