Interrupt
5.4 Return from Interrupt Routine
5.4 Return from Interrupt Routine
As you execute the REIT instruction at the end of the interrupt routine, the contents of the flag register
(FLG) and program counter (PC) that have been saved to the stack area immediately preceding the inter-
rupt sequence are automatically restored. Then control returns to the routine that was under execution
before the interrupt request was acknowledged, and processing is resumed from where control left off. If
there are any registers you saved via software in the interrupt routine, be sure to restore them using an
instruction (e.g., POPM instruction) before executing the REIT instruction.
