am using DS1307 RTC chip , after 1 or 2 days time is not changing , it is on same state , eg :5:59 pm, it is not incrementing , still same time even after 5hrs , and at this time Xtel pin is always DC voltage there is no sine wae at Xtel pin , i think Osscilator is in off state , when we are trying to write 0x00 in 0th location , it will start counting agian ,
my software logic is am reading I2C data two times in each second .
in some clock ther is no problem ,
