I use uart1 in isr mode, I send a character from computer, then I can capture a RXNE interrupt and recieve the character in uart1 isr, it work well.
But a error occur when I open a uart1 register windows. (select veiw->system viewer->usart->usart1, open the uart1 register windows) I can capture a uart1 interrupt but not a RXNE interrupt when I send a character from computer with the uart1 register windows.
It is a bug? I use keil 4.70
