Interrupts INT_00 through INT_03 are non-maskable and fixed.
Interrupts INT_04 through INT_15 are programmable by modifying the binary selector values in the Interrupt Selector Control registers fields.
Table 2
22 shows the default interrupt sources for Interrupts INT_04 through INT_15. For more detailed information on interrupt sources and
selection, see the
TMS320C6000 DSP Interrupt Selector Reference Guide
(literature number SPRU646).
