Nishant, AFAIK, the time between XRDY/XDR and setting of XUDF bit is not deterministic, it depends on the I2C bus speed but I am not sure if we can translate the speed into a fixed count number which we can use as a timeout limit. In that case we need to make a balanced assumption of the count value so that we don't fall in the timeout case under normal operation. May be someone can give a pointer here.

If not then it will keep running into timeout errors. > Do you mean we need a delay for checking again? that should be easy to incorporate - what kind of delay are we speaking of here? do you have a count requirement for handling this? it is essentially the time b/w XRDY to XUNDF.. this should be deterministic rt?
