Figure 12. Continuous mode

3.5.4

Continuous-to-FIFO mode

In Continuous-to-FIFO mode (FIFO_CTRL (2Eh)(FMODE [2:0] = 011), FIFO behavior

changes according to the INT_GEN_SRC_XL (26h)(IA_XL) bit. When the

INT_GEN_SRC_XL (26h)(IA_XL) bit is equal to '1', FIFO operates in FIFO-mode, when the

INT_GEN_SRC_XL (26h)(IA_XL) bit is equal to '0', FIFO operates in Continuous mode.

The interrupt generator should be set to the desired configuration by means of

INT_GEN_CFG_XL (06h), INT_GEN_THS_X_XL (07h), INT_GEN_THS_Y_XL (08h) and

INT_GEN_THS_Z_XL (09h).

The CTRL_REG4 (1Eh)(LIR_XL) bit should be set to '1' in order to have latched interrupt.
