Hi Al,

now I see your misunderstanding.

Pleae look at the starting of this thread.

The question was clearly, that a high level interrupt interupts a low level interrupt and so 2 interrupt in progress. Then you need 2 RETI.

If you forgot this and assumed, there is only 1 interupt in progress naturally a single RETI works. Then it plays no role, if this interrupt was high level or low level.

If you not want to answer the start question of a thread, please open better a new thread.
