With a MC9S08GT60 connected to a Modbus network SCI interruption SCI stop to work

[euge]

The main soft always works properly, is connected to a RS485 Modbus network, and SCI interrupt regularly receives inquiries. Randomly SCI interrupt crashes, everything still works well but the interruption is not activated. If you turn off and on  all work well again, the same if you activate RESET Pin. If I try with the _Startup() function the main soft start OK but not

work the SCI interrupt.

Best Regards

Hi Eugenio

please check that all the flag are clean, if you have set any flag on the SCI, the interrupt will not work until you clean all the flags.

Regarding to the _Startup() and POR, I already put my comments on the other thread.
