    Running RTC independently via coin battery?



      I am using a PSOC5LP and I have some questions on the implementation of sleep mode and running RTC independently. 


      I want to turnoff the main power of the MCU and run the RTC independently via a coin battery in sleep mode. Is it possible? 


      In other words, the coin battery is always connected to Vbat and when the main power supply of the mcu is turneddown, can the coin battery run RTC in sleep mode as an independent block without the need of the connection to main power supply?
