AN4506

5.1

Interrupt pin configuration

The device is provided with two pins which can be activated to generate either the data-

ready or the interrupt signals. The functionality of the pins is selected through CTRL3(22h).

Refer to Table 16, Table 17 and to the block diagram in Figure 11 for more details.

INT1_IG

Table 16. CTRL3 register

INT1_Boot H_Lactive

PP_OD INT2_DRDY INT2_FTH INT2_ORun INT2_Empty

Table 17. CTRL3 description

INT1_IG
