12.4.

RESTRICTIONS ON BREAKS IN THE INTERRUPT HANDLING ROUTINE

The following restrictions are imposed on breaks in the interrupt handling routine:

1) During a break, all maskable interrupts are rejected.

2) The single step function sets a temporary breakpoint in the next instruction. So, when a user

program placed in the EI (interrupt enable) state is subject to single stepping, an interrupt is accepted

even during single stepping.

3) After a break in the interrupt handling routine, exiting from the interrupt handling routine by single

stepping is impossible. (Specifically, single stepping based on the last "}" of the interrupt handling

routine is disabled.) Similarly, IRET instruction single stepping is impossible.

4) The Return function of the debugger does not support return from an interrupt handling routine to the

original routine.
