FIFO

Continuous (Dynamic-Stream)-to-FIFO mode

In Continuous (Dynamic-Stream)-to-FIFO mode (FIFO_CTRL (13h)(TRIG_MODES and

F_MODE[1:0] = ‘111’), data are stored in FIFO and FIFO operates in Continuous (Dynamic-

Stream) mode behavior until it switches to FIFO mode behavior when INT_SOURCE

(24h)(IA) rises to '1'.

An interrupt generator has to be set to the desired configuration through INTERRUPT_CFG

(0Bh).

Retrieving data from FIFO

FIFO data is read through FIFO_DATA_OUT_PRESS (78h, 79h and 7Ah) and

FIFO_DATA_OUT_TEMP (7Bh, 7Ch).

The read address is automatically updated by the device and it rolls back to 78h when

(5 output registers by 128 levels) must be read.
