May 25, 2018 at 12:53	comment	added	Juraj♦		@EdgarBonet, I did read your answer and it is correct. I answer other point of view, not what he coded, but what he wants to achieve (second comment). He doesn't want to reset the program, only the 'state of the program'.
May 25, 2018 at 12:47	comment	added	Edgar Bonet		Did you read my answer? `__init()` completely resets the state of the program. There is no “after the interrupt”: since `__init()` does not return, the following `reti` (return from interrupt) instruction will never be executed. And there is no “state where it was before interrupt”: that state was on the stack, and the stack is reset by `__init()`.
