controller to prioritize and control all system events. Conceptu-
ally, interrupts from the peripherals enter into the SIC and are
then routed directly into the general-purpose interrupts of the
CEC.
Core Event Controller (CEC)
The CEC supports nine general-purpose interrupts (IVG15–7),
in addition to the dedicated interrupt and exception events. Of
these general-purpose interrupts, the two lowest-priority
interrupts (IVG15–14) are recommended to be reserved for
software interrupt handlers, leaving seven prioritized interrupt
inputs to support the peripherals of the processor.
describes the inputs to the CEC, identifies their names in the
event vector table (EVT), and lists their priorities.
System Interrupt Controller (SIC)
The system interrupt controller provides the mapping and rout-
ing of events from the many peripheral interrupt sources to the
prioritized general-purpose interrupt inputs of the CEC.
Although the processor provides a default mapping, the user
can alter the mappings and priorities of interrupt events by writ-
ing the appropriate values into the interrupt assignment
registers (SIC_IARx).
and the default mappings into the CEC.
