TMP102 Accessing from User Space in Linux

I am trying to access TMP102 IC from userspace in DRA7xx_EVM, actually when i am writing writing 0x0 address first on the bus and reading 2 bytes of temp register i am getting the same value i.e., byte1 of temp register.. To read the entire temperature register i am writing 0x0 then read byte1,0x1 and then read byte2 of temp register..

But, actually in the data sheet if you see timing diagrams, its different...Am I accessing wrongly ??

2. The default values of config register are different from what mentioned in the data sheet..

Thanks & Regards,

Ganesh.
