Section 4.0 “Memory Organization”
this data sheet for device-specific register
and bit information.
Several of the registers cited in this section are not in the interrupt controller module. These registers (and
bits) are associated with the CPU. Details about them are available in
To avoid confusion, a typographic distinction is made for registers in the CPU. The register names in this
section, and all other sections of this manual, are signified by uppercase letters only. The CPU register
names are signified by upper and lowercase letters. For example, INTSTAT is an Interrupts register;
whereas, IntCtl is a CPU register.

Priority Level
PIC32MX3XX/4XX devices generate interrupt requests
in response to interrupt events from peripheral mod-
ules. The Interrupt Control module exists externally to
the CPU logic and prioritizes the interrupt events before
presenting them to the CPU.
The PIC32MX3XX/4XX interrupts module includes the
following features:
• Up to 96 interrupt sources
• Up to 64 interrupt vectors
• Single and Multi-Vector mode operations
• Five external interrupts with edge polarity control
• Interrupt proximity timer
• Module Freeze in Debug mode
• Seven user-selectable priority levels for each
• Four user-selectable subpriority levels within each
• Dedicated shadow set for highest priority level
• Software can generate any interrupt
• User-configurable interrupt vector table location
• User-configurable interrupt vector spacing
