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?

Hi @ggob ,

Once the device configuration is completed and stable, this bit can be set back to 0 if no further configuration changes are expected.

Thank you very much. This is very helpful.
Is it necessary to set this bit to “1” before setting it to “1” by operating BOOT or SW_RESET of CTRL3_C?
