Forum Post: RE: Interrupt Clearing - Repeated execution of ISR

[quote user="mil meh"]

try this:

if(ulStatus & UART_INT_RX || ulStatus & UART_INT_RT)     {

while (MAP_UARTCharsAvail(UART0_BASE) {

    data[i] = (char)MAP_UARTCharGetNonBlocking(UART0_BASE); // Read a character
     }

    }

I dont want to read a char just yet, I just want to increment the counter and leave the ISR.

If i use the 'UARTCharGetNonBlocking' its working fine, if i remove it repeatedly enters the ISR.

For the time being i left the function 'UARTCharGetNonBlocking' in the code. But i just didnt understand what am i doing wrong.
