TOUT[15:8] This register contains the high part of the temperature output value.
The temperature output value is a 16-bit data that contains the measured temperature. It is
composed by TEMP_OUT_H (2Ch) and TEMP_OUT_L (2Bh). The value is expressed as
2’s complement.

FIFO_MEAN mode: The FIFO can be used for implementing a HW moving average on the
pressure measurements. The number of samples of the moving average can be 2, 4, 8, 16
or 32 samples by selecting the watermark levels as per Table 22. Different configurations are
not allowed.
