Power saving modes
Introduction
To give a large measure of flexibility to the application in terms of power consumption, four
main power saving modes are implemented in the ST7 (see
●

●
●
After a reset the normal operating mode is selected 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 (f
From Run mode, the different power saving modes may be selected by setting the relevant
register bits or by calling the specific ST7 software instruction whose action depends on the
oscillator status.
