Veena, it seems like you're making progress. However, when you talk about random numbers being displayed, we need a bit more information - like are all the register you read get garbled data? How often? What are the numbers vs what you expect? This information is critical in order to try and diagnose the problem. In fact, with this information, you should be able to at least narrow the problem down. For example:- if the minutes get garbled every minute, maybe its something to do with an internal update in the chip. Some chips expect certain registers to be read in a certain order, others like you to turn a bit on or off in a register to 'freeze' the current time being read out.

Also, if you can post the simplest piece of code that has the problem, then we can maybe identify a problem there.

Its a bit like phoning up the doctor saying "i'm ill" and expecting him to know exactly what your problem is. Please don't expect us to magically know what your problem is.
