SPRS357A–AUGUST 2006–REVISED OCTOBER 2006
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 28044 device, 43 of these are used by
peripherals as shown in
Table 3-8

Out of the 96 possible interrupts, 43 interrupts are currently used. The remaining interrupts are reserved for future devices. These
interrupts can be used as software interrupts if they are enabled at the PIEIFRx level, provided none of the interrupts within the group is
being used by a peripheral. Otherwise, interrupts coming in from peripherals may be lost by accidentally clearing their flag while
modifying the PIEIFR. To summarize, there are two safe cases when the reserved interrupts could be used as software interrupts:
1.
No peripheral within the group is asserting interrupts.
2.
No peripheral interrupts are assigned to the group (example PIE group 12).
