TI中文支持网C6748想要进入睡眠状态，只保留RTC电路作为值守电路，请问该怎么设置？
Tony Tang：
RTC单独供电，不要断电就好了。
The RTC has a power supply that is isolated from the rest of the system. This allows the RTC to continueto run while the rest of the system is not powered. In this state, the RTC time and calendar counterscontinue to run, but the powered down CPU is not able to receive RTC interrupts. Separate power supplypins for the RTC are provided on the device package.
