I am working on these issue from couple of days and i am not able to figure why it is happening so.
On reset all the RTC registers (seconds,minutes,hours days,alm ) are reseting to zero. In the manual it is given as the values will be arbitary .So I expected on reset the values would be same before the shutdown but it is reseting on each power on and also reset. Can some body explain about this .
my plan is to provide back up using battery for the RTC and make it to run continously to maintain real time .
I am also including the intailizatiopn code here.
MCF_CLOCK_RTCDR = ( (SYSTEM_CLOCK_KHZ * 1000 ) ) /* for configuring tjhe clock */
MCF_RTC_RTCCTL = (MCF_RTC_RTCCTL_EN ) ;
MCF_SCM_PPMRL &= (0xFFFFEFFF) ; /* enables the RTC*/
Please help me......i am stuck at this simple thing............
Thanks for your time
