Figure 10. FIFO mode

7.2.3

Continuous mode

Continuous mode (FIFO_CTRL (2Eh)(FMODE[2:0] = 110) provides a continuous FIFO

update: as new data arrives, the older is discarded.

A FIFO threshold flag FIFO_SRC (2Fh)(FTH) is asserted when the number of unread

samples in FIFO is greater than or equal to FIFO_CTRL (2Eh)(FTH4:0).

It is possible to route FIFO_SRC (2Fh)(FTH) to the INT1 pin by writing the INT_FTH bit to ‘1’

in register INT1_CTRL (0Ch).

A full-flag interrupt can be enabled, INT1_CTRL (0Ch) (INT_ FSS5)= '1', when the FIFO

becomes saturated and in order to read the contents all at once.

If an overrun occurs, the oldest sample in FIFO is overwritten and the OVRN flag in

FIFO_SRC (2Fh) is asserted.

In order to empty the FIFO before it is full, it is also possible to pull from FIFO the number of

unread samples available in FIFO_SRC (2Fh) (FSS[5:0]).
