TEMP_OUT_H (2Ch)

Temperature output value (MSB)

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_CTRL (2Eh)

FIFO control

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.
