The current interrupt mask in LVTS_MONINT_CONF, enables many more interrupts, including data ready on sensors for both filtered and immediate mode. These are not only not handled by the driver, but they are also triggered too often, causing unneeded overhead. Disable these unnecessary interrupts. The meaning of each bit can be seen in the comment describing LVTS_MONINTST in the IRQ handler.
