mm9z1_638 offset step over the range

[a852013777]

Hi Nxp partner

After we perform the calibration process for PTB ,we get the offset step is 7271 and gainstep is 1.

The range of Offset compensation is only -128~127. Offset step is 7271 is bigger than 127.

We cannot write 7271 to Offset compensation (offset ch ).

Can we first set offset compensation(offset ch ) to zero and then

add  ptb offset compensation formula   (see the attached file.   before sending ptb 

measurement value .

Br,
