10.2.1 Overview
The Nested Vectored Interrupt Controller (NVIC) in the PIC32CX SG41/SG60/SG61 family of devices supports 138 interrupts with eight different priority levels. For additional information, refer to the “Cortex-M4 Technical Reference Manual”, which is available for download at www.arm.com.
