interrupt sources and interrupt selector
The C62x DSP core supports 16 prioritized interrupts, which are listed in Table 16. The highest-priority interrupt
is INT_00 (dedicated to RESET) while the lowest-priority interrupt is INT_15. The first four interrupts
(INT_00
INT_03) are non-maskable and fixed. The remaining interrupts (INT_04
INT_15) are maskable and
default to the interrupt source specified in Table 16. The interrupt source for interrupts 4
15 can be programmed
by modifying the selector value (binary value) in the corresponding fields of the Interrupt Selector Control
registers: MUXH (address 0x019C0000) and MUXL (address 0x019C0004).

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 16 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).
