C281x Hardware Interrupt

Each interrupt is represented b y one element from each parameter (four

elements total), one from the same position in each of these vectors.

Each interrupt is described by:

• CPU interrupt numbers

• PIE interrupt numbers

• Task priorities

• Preemption ﬂags

So one interrupt is described by a CPU interrupt number, a PIE

interrupt number, a task priority, and a p reemption ﬂag.

The CPU and PIE interrupt numbers together uniquely specify a single

interrupt for a single periphera l or perip h era l m odule. The fo llowing

table maps CPU and PIE interrupt numbers to these peripheral

interrupts.
