6 POWER SAVING MODES
6.1 INTRODUCTION
To give a large measure of flexibility to the applica-
Figure 19. Power Saving Mode Transitions
tion in terms of power consumption, two main pow-
er saving modes are implemented in the ST6 (see
High
Figure
19).
RUN
In addition, the Low Frequency Auxiliary Oscillator
(LFAO) can be used instead of the main oscillator
to reduce power consumption in RUN and WAIT
LFAO
modes.
After a RESET the normal operating mode is se-
WAIT
lected by default (RUN mode). This mode drives
the device (CPU and embedded peripherals) by
means of a master clock which is based on the
main oscillator frequency.
STOP
From Run mode, the different power saving
Low
modes may be selected by calling the specific ST6
POWER CONSUMPTION
software instruction or for the LFAO by setting the
relevant register bit. For more information on the
LFAO, please refer to the Clock chapter.
