Hi this is my second posted Thread on this Forum.

The problem is i belive my PIC 18F452 is reseting it's self every 20 to 30 interrupts it recives via RS232. Is this possible?
Or is the reset a result off overflowing Stack?

The µController has to carry out several HSEROUT and A/D operations after receiving an interrupt .
I do not know if this data is stored on the PIC after ist send or read?

Many thanks
