Event Handling
The event controller on the Blackfin processor handles all asyn-
chronous and synchronous events to the processor. The
Blackfin processor provides event handling that supports both
nesting and prioritization. Nesting allows multiple event service
routines to be active simultaneously. Prioritization ensures that
servicing of a higher priority event takes precedence over servic-
ing 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.
Nonmaskable 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 (in other words, 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 Blackfin processor event controller consists of two stages:
the core event controller (CEC) and the system interrupt con-
troller (SIC). The core event controller works with the system
interrupt controller to prioritize and control all system events.
Conceptually, interrupts from the peripherals enter into the
SIC, and are then routed directly into the general-purpose inter-
rupts of the CEC.
