The DSP C66x CorePac includes an interrupt controller (DSP_INTC) and can receive a total of 128 system events as inputs. They include DSP-generated events and chip-level events.
In addition to these 128 events, a non-maskable (NMI) event (see the Section 5.3.4.1.1) and reset events are mapped to the DSP_INTC as well, and are routed straight through to the DSP CPU core.
For more details on the DSP_INTC functionalities and its corresponding control / status registers (part of the DSP_ICFG local configuration space), refer to the section Interrupt Controller within the TMS320C66x DSP CorePac User Guide, ( SPRUGW0C).
For more details on input interrupt mappings and associated IRQ wake-up events, refer to the Section 5.3.4.1.
For more information about the device DSP_INTC, see Interrupt Controllers. For more information on chip level IRQ mapping via the device IRQ_CROSSBAR module, see IRQ_CROSSBAR Module Functional Description, in Control Module.
