Interrupts
shows how the various interrupt sources are multiplexed within the F2812 device.
Figure 3-4. Interrupt Sources
Eight PIE block interrupts are grouped into one CPU interrupt. In total, 12 CPU interrupt groups, with 8
interrupts per group equals 96 possible interrupts. On the F2812, 45 of these are used by peripherals as
shown in
