higher-priority event takes precedence over servicing of a lower-
priority event. The controller provides support for five different
types of events:
Emulation. An emulation event causes the processor to
enter emulation mode, allowing command and control of
the processor via the JTAG interface.
Reset. This event resets the processor.
Non-maskable interrupt (NMI). The NMI event can be
generated by the software watchdog timer or by the NMI
input signal to the processor. The NMI event is frequently
used as a power-down indicator to initiate an orderly shut-
down of the system.
Exceptions. Events that occur synchronously to program
flow (that is, the exception is taken before the instruction is
allowed to complete). Conditions such as data alignment
violations and undefined instructions cause exceptions.
Interrupts. Events that occur asynchronously to program
flow. They are caused by input pins, timers, and other
peripherals, as well as by an explicit software instruction.
Each event type has an associated register to hold the return
address and an associated return-from-event instruction. When
an event is triggered, the state of the processor is saved on the
supervisor stack.
The ADSP-BF54x Blackfin processor event controller consists
of two stages, the core event controller (CEC) and the system
interrupt controller (SIC). The core event controller works with
the system interrupt controller to prioritize and control all sys-
tem events. Conceptually, interrupts from the peripherals enter
into the SIC and are then routed directly into the general-pur-
pose 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 inter-
rupts (IVG15–14) are recommended to be reserved for software
interrupt handlers, leaving seven prioritized interrupt inputs to
support the peripherals of the ADSP-BF54x Blackfin processors.
Table 3 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 ADSP-BF54x Blackfin processors provide a
default mapping, the user can alter the mappings and priorities
of interrupt events by writing the appropriate values into the
interrupt assignment registers (SIC_IARx). Table 4 describes
the inputs into the SIC and the default mappings into the CEC.
