LSM6DSV80X gyro offset

I am using the LSM6DSV80X to get roll-pitch-yaw from SFLP and gyro reading. I noticed that the sensor keeps reporting increasing yaw and increasing offset for X axis while at rest even though the data sheet suggests that it should have up to only 1dp...

Resolved! STATUS_REG of the ASM330LHH

How long does the TDA bit in the STATUS_REG of the ASM330LHH remain “1”?Is the TDA bit itself a latch type and remains “1” until the temperature output register (OUT_TEMP_H/L, 21h/20h) is read?

Resolved! ASM330LHH CTRL9_XL DEVICE_CONF

It is recommended that CTRL9_XL DEVICE_CONF in ASM330LHH always set this bit to 1 when configuring the device, but when should it be set back to 0? Should it not be set back?
