Register 0x2A and 0x2B are aways fixed when I read back register even with restarting the sensor power.

Config before reading back register:

Register_0x20=0x83: (active mode, continuous update, output data rate: 12.5Hzt

Register_0x21=0x01: (Boot normal mode, Heater disable, start of new dataset)

Register_0x22=0x84: (DRDY active low, PP_OD push pull, Data Ready signal available on pin 3)

The dataready pin is also always low, command Who AM I works fine.

Content of register 0x2A: 0x18;

Content of register 0x2B: 0x80;

Does anyone has the same pb ? Is the chip dead ?

The data is updated every register reading, I had a problem with the writing function. However my data ready signal is always low. 

About the calibration factor: 

Is the T0_degC_x8 always inferior to T1_degC_x8 ?
