The device features one set of programmable interrupt sources (INT) that can be configured

to trigger different pressure events. Figure 19 shows the block diagram of the interrupt

generation block and output pressure data.

The device may also be configured to generate, through the INT_DRDY pin, a Data Ready

signal (DRDY) which indicates when a new measured pressure data is available, thus

simplifying data synchronization in digital systems or optimizing system power consumption.

Interrupt configuration

76543210

0000F_EMPTYF_FTH F_OVR DRDY

F_EMPTY FIFO empty flag on INT_DRDY pin. Default value: 0.

(0: disable; 1: enable)

F_FTH FIFO threshold (watermark) status on INT_DRDY pin to indicate that FIFO is filled

up to the threshold level. Default value: 0.

(0: disable; 1: enable)

F_OVR FIFO overrun interrupt on INT_DRDY pin to indicate that FIFO is full in FIFO mode

or that an overrun occurred in Stream mode. Default value: 0.

(0: disable; 1: enable)

DRDY Data-ready signal on INT_DRDY pin. Default value: 0.

(0: disable; 1: enable)
