    Hello,

    Once my UART interrupts the processor (STR9), nothing else other than interrupt handling occurs! I tried it using a loopback and a simulation of input signals (I use Keil microvision) but still - the result is the same!

    My ISR looks like this:

    Code:

    unsigned x = UART0->DR ;

    UART_ClearITPendingBit(UART0, UART_IT_Receive) ;

    VIC0->VAR = 0 ;

    VIC1->VAR = 0 ;

    }

    How come do I keep on getting interrupted? Am I cleaning up inappropriately?
