Interrupts and Exceptions
5.7 Interrupt Definitions
Table 5-6 summarizes each interrupt type, the various exception types that may cause that
interrupt, the interrupt classification, which ESR bits can be set, which MSR bits can mask the
interrupt type, and which IVOR is used to specify the vector address.
