BQ27421 hibernate problem

Hi,

I am using BQ27421 to measure battery percentage (State of charge).

When system goes to sleep mode , I am putting BQ27421 into hibernate mode, It's also going into hibernate mode.

But When system wakes up and sends command to fuel gauge to clear hibernate bit, it wakes up but it shows wrong value of charge.

Before going to hibernate value was 0E, after coming out it was 03.

When I reset the system and configure it again value comes correctly (0C).

Does anybody has this issue? Any solution to this problem?

EDIT: Also another question is I am reading value from address  0x1C (SOC register) and I am printing it. But it shows wrong value. (May be fuelgauge is not calibrated).

Thanks.
