7.0
The
dsPIC33FJ64GS406/606/608/610 interrupt controller
reduces the numerous peripheral interrupt request
signals to a single interrupt request signal to the
dsPIC33FJ32GS406/606/608/610
dsPIC33FJ64GS406/606/608/610 CPU. It has the
following features:
• Up to eight processor exceptions and software
• Seven user-selectable priority levels
• Interrupt Vector Table (IVT) with up to 118 vectors
• A unique vector for each interrupt or exception
• Fixed priority within a specified user priority level
• Alternate Interrupt Vector Table (AIVT) for debug
• Fixed interrupt entry and return latencies
7.1
The Interrupt Vector Table (IVT) is shown in Figure 7-1.
The IVT resides in program memory, starting at location
000004h. The IVT contains 126 vectors, consisting of
eight nonmaskable trap vectors, plus up to 118 sources
of interrupt. In general, each interrupt source has its own
vector. Each interrupt vector contains a 24-bit-wide
address. The value programmed into each interrupt
vector location is the starting address of the associated
Interrupt Service Routine (ISR).

Preliminary
Interrupt vectors are prioritized in terms of their natural
priority. This priority is linked to their position in the
vector table. Lower addresses generally have a higher
natural priority. For example, the interrupt associated
with vector 0 will take priority over interrupts at any
other vector address.
The
dsPIC33FJ64GS406/606/608/610 devices implement up
to 71 unique interrupts and five non-maskable traps.
These are summarized in Table 7-1.
7.1.1
The Alternate Interrupt Vector Table (AIVT) is located
after the IVT, as shown in Figure 7-1. Access to the
AIVT
(INTCON2<15>). If the ALTIVT bit is set, all interrupt
and exception processes use the alternate vectors
instead of the default vectors. The alternate vectors are
organized in the same manner as the default vectors.
The AIVT supports debugging by providing a means to
switch between an application and a support
environment without requiring the interrupt vectors to
be reprogrammed. This feature also enables switching
between applications for evaluation of different
software algorithms at run time. If the AIVT is not
needed, the AIVT should be programmed with the
same addresses used in the IVT.
7.2
A device Reset is not a true exception because the
interrupt controller is not involved in the Reset process.
The
dsPIC33FJ64GS406/606/608/610
registers in response to a Reset, which forces the PC to
zero. The digital signal controller then begins program
execution at location 0x000000. A GOTO instruction at the
Reset address can redirect program execution to the
appropriate start-up routine.
