9.0
PIC32MX Family generates interrupt requests in
response to interrupt events from peripheral modules.
The interrupts module exists external to the CPU logic
and prioritizes the interrupt events before presenting
them to the CPU.

This data sheet summarizes the features of
the PIC32MX family of devices. It is not
intended to be a comprehensive reference
source. Refer to the “PIC32MX Family
detailed description of this peripheral.
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 2.0. “CPU”.
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.
