TEMP_OUT_H

Temperature data (MSB)

Address:

2Ch (R)

Description:

The TEMP_OUT_H register contains the high part of the temperature output

value.(See description TEMP_OUT_L).

7.18

FIFO_CTRL

FIFO control

Address:

2Eh (R/W)

Reset:

00h

Description:

The FIFO_CTRL registers allows to control the FIFO functionality.

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 21. Different configuration are

not guaranteed

FIFO_MEAN MODE: FIFO is used to generate a running average filtered

pressure

BYPASS mode until trigger deasserted, then change to FIFO MODE
