The default sources of the 128 device events are shown in Table 7-29. In addition, device events 15 through 95 can alternatively be sourced from one of the 24 Multiplexed device events shown in Table 7-30. The DSP_INTMUX_x registers in the Control Module are used to select between the default event and the multiplexed event. The interrupt controller also controls the generation of the CPU exceptions, NMI, and emulation interrupts. Table 7-29.
