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 25 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).
