5.4 Returning from Interrupt Routines
Chapter 5
When the REIT instruction is executed at the end of the interrupt routine, the contents of the FLG register
and PC that have been saved to the stack area immediately preceding the interrupt sequence are automati-
cally restored. Then control returns to the routine that was under execution before the interrupt request was
acknowledged.
If any registers were saved in the interrupt routine using a program, be sure to restore them using an
instruction (e.g., the POPM instruction) before executing the REIT instruction.
