CPU Interrupts Overview

3-3CPU Interrupts and Reset

Fetch the interrupt vector and load it into the program counter (PC).

For devices with a PIE module, the vector fetched will depend on the

setting of the PIE enable and flag registers.

4) Execute the interrupt service routine. The C28x branches to its corre-

sponding subroutine called an interrupt service routine (ISR). The C28x

branches to the address (vector) you store at a predetermined vector loca-

tion and executes the ISR you have written.
