Please see the attached code in "Testice.bas".

The external interrupt INT0 is still enabled in spite of the instruction in the line after "Waitmse 690". No error message after compilation.
Can anyone explain why?
Best Regards

disable INT0 will disable the interrupt enable bit in the IE register. but ... if a flag was still pending, the interrupt will still be called once.
so clear the flag in TCON.1 to prevent that the isr is called.
