5.0 INTERRUPT CONTROLLER

Note:

This data sheet summarizes the features

of the PIC32MX1XX/2XX/5XX 64/100-pin

family of devices. It is not intended to be

a comprehensive reference source. To

complement the information in this data

sheet, refer to Section 8. “Interrupt

Controller” (DS60001108) in the “PIC32

Family Reference Manual”, which is

available from the Microchip web site

(www.microchip.com/PIC32).

PIC32MX1XX/2XX/5XX 64/100-pin devices generate

interrupt requests in response to interrupt events from

peripheral modules. The interrupt control module exists

externally to the CPU logic and prioritizes the interrupt

events before presenting them to the CPU.

The PIC32MX1XX/2XX/5XX 64/100-pin interrupt

module includes the following features:

• Up to 76 interrupt sources

• Up to 46 interrupt vectors

• Single and multi-vector mode operations

• Five external interrupts with edge polarity control

• Interrupt proximity timer

• Seven user-selectable priority levels for each

vector

• Four user-selectable subpriority levels within each

priority

• Software can generate any interrupt

• User-configurable interrupt vector table location

• User-configurable interrupt vector spacing

Note: The dedicated shadow register set is not

available on these devices.
