The PIC24HJXXXGPX06/X08/X10 interrupt controller
reduces the numerous peripheral interrupt request
signals to a single interrupt request signal to the
PIC24HJXXXGPX06/X08/X10 CPU. It has the follow-
ing 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
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
8 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).
Interrupt vectors are prioritized in terms of their natural
priority; this priority 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 associated with vector 0 will take priority
over interrupts at any other vector address.
PIC24HJXXXGPX06/X08/X10 devices implement up
to 61 unique interrupts and 5 nonmaskable traps.
These are summarized in Table 7-1 and Table 7-2.

This data sheet summarizes the features
of the PIC24HJXXXGPX06/X08/X10 fam-
ily of devices. However, it is not intended
to be a comprehensive reference source.
To complement the information in this data
sheet, refer to the “PIC24H Family Refer-
ence Manual”, Section 6. “Interrupts”
(DS70224), which is available from the
Microchip website (www.microchip.com).

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 environ-
ment without requiring the interrupt vectors to be
reprogrammed. This feature also enables switching
between applications for evaluation of different soft-
ware 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 PIC24HJXXXGPX06/X08/X10 device clears its
registers in response to a Reset which forces the PC to
zero. The digital signal controller then begins program
execution at location 0x000000. The user programs a
GOTO instruction at the Reset address which redirects
program execution to the appropriate start-up routine.

Any unimplemented or unused vector
locations in the IVT and AIVT should be
programmed with the address of a default
interrupt handler routine that contains a
RESET instruction.
