10. Interrupt Controller (INTC)
Table 10.12 IRL Interrupt Pins (IRL[3:0], IRL[7:4]) and Interrupt Levels
IRL interrupt detection requires an on-chip noise-cancellation feature. This detection is performed
when the level sampled at every bus clock is the same for three consecutive cycles. This detection
can prevent the incorrect level from being taking in when the IRL interrupt pin state changes.
