112 / 227 page  TMS320DM6446 SPRS283H – DECEMBER 2005 – REVISED SEPTEMBER 2010 www.ti.com 6.7.2 DSP Interrupts The C64x+ DSP interrupt controller combines device events into 12 prioritized interrupts. The source for each of the 12 CPU interrupts is user programmable and is listed in Table 6-22. Also, the interrupt controller controls the generation of the CPU exception, NMI, and emulation interrupts. Table 6-23 summarizes the C64x+ interrupt controller registers and memory locations. For more details on DSP interrupt control, see the TMS320DM644x DMSoC DSP Subsystem Reference Guide (literature number SPRUE15). Table 6-22.
