Figure 10. Interrupt controller block diagram

The system’s interrupt controller uses the corresponding bit field in the CTRL_REG5 register to determine the routing for the INT1

and INT2 interrupt pins. For example, if the int_cfg_drdy bit value is logic ‘0’ the functional block’s interrupt is routed to INT2, and

if the bit value is logic ‘1’ then the interrupt is routed to INT1. All interrupt signals routed to either INT1 or INT2 are logically OR’ed

together as illustrated in Figure 11, thus one or more functional blocks can assert an interrupt pin simultaneously; therefore a

host application responding to an interrupt should read the INT_SOURCE register to determine the source(s) of the interrupt(s).
