7.0
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.

“Interrupt Controller” (DS61108) for a
detailed description of this peripheral.
The manual is available from the Microchip
web site (www.Microchip.com/PIC32).
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 Section 3.0 "PIC32MX MCU".
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.CPU register names
are signified by upper and lowercase letters. For example, INTSTAT is an Interrupts register; whereas,
IntCtl is a CPU register.
