Hi everyone,
I dont know what should I do to let the keil compiler know refer to which function when interrupt occur. I know interrupt functions are followed with _irq prefix but there may be several of these functions!
Dear all friends,
Thanks for your helpful advises. Yes I see that the function USARTInit() installs my usart function 'UART0Handler' in the VIC table by following code:
if ( install_irq( UART0_INT, (void *)UART0Handler ) == FALSE ) { return (FALSE); }
