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 divided or multiplied by 2 (fOSC2). 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. Figure 21. Power saving mode transitions Power consumption Wait Slow Run Active Halt High Low Slow Wait Halt Obsolete Product(s) - Obsolete Product(s) |
