    I have a problem in my application which , I suppose , refers to wrong interrupts initialization.

    In my program I have external interrupts , timer A interrupts , SCI ( UART interupts ) and in continuation - SPI interrupts.

    I don't exactly know how even to define my problem.

    The following scenario keeps repeating itself:

    - The program works , the interrupts are executed

    - I decide to tak step forward and made some change/ addition in the algorithm

    - The program stops wrokin correctly

    - I revert the changes i've made , but the program still doesn't work

    - After number of random corrections ( usually associated with interrupts ) the program starts working correctly again.

    - And from the beginning........

    Is there any determine sequence for interrupts service initialization?

    Please help , the isuue is very urgent.

    I use ST72F321BAR9 micro

    I debug using InDART.

    :-? :-? :-?

    By now i have a problem adding SCI interrupt

    Without SCI interrupt - external source interrupts work correctly
