Figure 3-5
shows how the various interrupt sources are multiplexed within the 280x devices.
Figure 3-5. External and PIE 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 280x, 43 of these are used by peripherals as
shown in
Table 3-10
.
