The power saving modes of the XC866 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
Figure
different power saving modes can be selected by software. They are:
• Idle mode
• Slow-down mode
• Power-down mode
