6 POWER SAVING MODES

6.1 INTRODUCTION

To give a large measure of flexibility to the applica-

tion in terms of power consumption, two main pow-

er saving modes are implemented in the ST6 (see

Figure 19).

In addition, the Low Frequency Auxiliary Oscillator

(LFAO) can be used instead of the main oscillator

to reduce power consumption in RUN and WAIT

modes.

After a RESET the normal operating mode is se-

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.

From Run mode, the different power saving

modes may be selected by calling the specific ST6

software instruction or for the LFAO by setting the

relevant register bit. For more information on the

LFAO, please refer to the Clock chapter.
