Reading IC Status register Failing

Hi Prashant,

Does the 1-wire signal look ok?  Is the IC responding to the presence pulse from the host?  Is the IC powered correctly?  I am not aware of anything that has changed in this device, so I would inspect your setup to compare what previously worked vs what is now not working.

Thanks,

Jason

Thanks for quick response....

YES..IC responding for presence pulse from the host.....

Wrt to hardware and software there are no changes....
Initially we had new batch IC assembled in the board....we were not getting 0xAF status register value....we were debugging what may be the issue....initially we checked hardware and software....it didn't resolved.....and next we thought there may be the issue with IC so we tried with different IC of same batch....but we still faced same issue.....3rd time we thought of using old batch IC....and this time we got status register, current and accumulated register values properly and it worked perfectly.....So we suspect there may be issue with new batch IC......
Is it possible to check whether new batch IC are working properly ....I want confirmation that, Are there any other customers which are using previously old batch and this time new batch IC's and is that worked for them.....?If it worked for them means then I will check my side.....
