Interrupt Controller
The C64x+ Megamodule includes an interrupt controller (INTC) to manage CPU interrupts. The interrupt
controller interfaces the system events to the CPU's interrupt and exception inputs. The interrupt controller
supports up to 128 system events, and it maps these system events to the 12 CPU interrupts. See the
device-specific data manual for the list of system events. The interrupt controller section of the
TMS320C64x+ DSP Megamodule Reference Guide (SPRU871 ) fully describes the INTC and how it maps
the DSP device events to the 12 CPU interrupts.
