Power Saving Modes
The power saving modes in the XC886/888 provide flexible power consumption through
a combination of techniques, including:
•
Stopping the CPU clock
•
Stopping the clocks of individual system components
•
Reducing clock speed of some peripheral components
•
Power-down of the entire system with fast restart capability
After a reset, the active mode (normal operating mode) is selected by default (see
) and the system runs in the main system clock frequency. From active mode,
different power saving modes can be selected by software. They are:
•
Idle mode
•
Slow-down mode
•
Power-down mode
