How can i maintain real time while using T1042. One of the options is to use external RTC lC. Can i do the same using the "RTC" pin of T1042? If yes, what clock frequency is required at its input? Moreover, in the case of external RTC normally a cell is used as backup power supply, what here will be used as backup supply if the processor is shut down? Thank you!
