6.0
The PIC24F interrupt controller reduces the numerous
peripheral interrupt request signals to a single interrupt
request signal to the PIC24F CPU. It has the following
features:
• Up to 8 processor exceptions and software traps
• 7 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
6.1
The Interrupt Vector Table (IVT) is shown in Figure 6-1.
The IVT resides in program memory, starting at location
000004h. The IVT contains 126 vectors, consisting of
8 non-maskable 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 vec-
tor location is the starting address of the associated
Interrupt Service Routine (ISR).
Interrupt vectors are prioritized in terms of their natural
priority; this is linked to their position in the vector table.
All other things being equal, lower addresses have a
higher natural priority. For example, the interrupt asso-
ciated with vector 0 will take priority over interrupts at
any other vector address.
PIC24FJ128GA010 family devices implement non-
maskable traps and unique interrupts. These are
summarized in Table 6-1 and Table 6-2.

6.1.1
The Alternate Interrupt Vector Table (AIVT) is located
after the IVT as shown in Figure 6-1. Access to the
AIVT
(INTCON2<15>). If the ALTIVT bit is set, all interrupt
and exception processes will 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 emulation and debugging efforts by
providing a means to switch between an application
and a support environment without requiring the inter-
rupt 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.
6.2
A device Reset is not a true exception because the
interrupt controller is not involved in the Reset process.
The PIC24F device clears its registers in response to a
Reset which forces the PC to zero. The microcontroller
then begins program execution at location 000000h.
The user programs a GOTO instruction at the Reset
address, which redirects program execution to the
appropriate start-up routine.

TABLE
Any unimplemented or unused vector
locations in the IVT and AIVT should be

interrupt handler routine that contains a
