BQ78350-R1A: Unable to write data to registers from SMBUS pin through CP2112 USB-SMBUS tool.

Part Number: BQ78350-R1A
Other Parts Discussed in Thread: BQ78350, BQ76930, BQSTUDIO

Hello all.

I am using fuel gauge IC bq78350 with AFE IC bq76930. I am using SMBUS to communicate.

I am unable to write to the data flash registers using CP2112.

Say for example as per the TRM, The CUV Threshold value is located at address 0x44CC, with a default value of 0x09C4(2500 mv)

When we read this register through the advanced comm Tab of BQStudio, the read happens as usual

and then we attempt to change the value to 0x0A28(2600 mv), which also gets executed.

and now we try to do the same through CP2112 tool, the read happens as shown below,

but when we write to it, the values aren't updated and when we check the transfer status, we get this, 

Could you please tell us the right way to change values in the data flash registers.

we have been sending 00 CC 44 00 00 0A 28 to address 0x44 with no luck.
