Booting
The processor contains a small on-chip boot kernel, which con-
figures the appropriate peripheral for booting. If the processor is
configured to boot from boot ROM memory space, the proces-
sor starts executing from the on-chip boot ROM. For more
information, see Booting Modes on Page 16.
Event Handling
The event controller on the processor handles all asynchronous
and synchronous events to the processor. The processor pro-
vides 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 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.
Nonmaskable Interrupt (NMI)—The NMI event can be
generated either by the software watchdog timer, by the
NMI input signal to the processor, or by software. The
NMI event is frequently used as a power-down indicator to
initiate an orderly shutdown 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 signals, 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, an interrupt service routine (ISR) must
save the state of the processor to the supervisor stack.
The 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 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. Table 2
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
routing 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
writing the appropriate values into the interrupt assignment
registers (SIC_IARx). Table 3 describes the inputs into the SIC
and the default mappings into the CEC.
