Chapter 17 Interrupt (INTV1) Block Description
17.2 External Signal Description
Most interfacing with the interrupt sub-block is done within the core. However, the interrupt does receive
direct input from the multiplexed external bus interface (MEBI) sub-block of the core for the IRQ and
XIRQ pin data.
17.3 Memory Map and Register Definition
Detailed descriptions of the registers and associated bits are given in the subsections that follow.
