7.Power saving operation mode
。Fast mode:slow clock can be disabled or enabled,and fast clock can keep the CPU running
。SLOW mode:Fast clock can be disabled or enabled,while slow clock can keep the CPU running
。Idle mode:Fast clock and CPU stop.Slow clock,Timer2 or wake-up timer continues to run
。STOP mode:All clocks stop,Timer2 and wake-up timer stop
