NAME
XG_OFFS_TC_L[7:0]]
FUNCTION
Bits 7 to 0 of the 10-bit offset of X gyroscope (2ꢋs complement)
Description:
The temperature compensation (TC) registers are used to reduce gyro offset variation due to temperature change.
The TC feature is always enabled. However, the compensation only happens when a TC coefficient is programed
during factory trim which gets loaded into these registers at power up or after a DEVICE_RESET. If these registers
contain a value of zero, temperature compensation has no effect on the offset of the chip. The TC registers have a
10-bit magnitude and sign adjustment in all full scale modes with a resolution of 2.52 mdps/C steps.
If these registers contain a non-zero value after power up, the user may write zeros to them to see the offset values

The above description also applies to registers 7-8 and 10-11.
