UART Tx interrupt

Hello,

I am using the UART0 in interrupt mode , the problem is that after sending the last byte and clearing the pending interrupt the Tx interrupt still occurs ( i am not using break mode ), I want to know how to stop the Tx interrupt after last byte ( not to disable interrupts). thanks

Hi usbmaster,

Could you change ''UARTx->ICR &= UART_IT'' by ''UARTx->ICR = UART_IT'' in UART_ClearITPendingBit function of 91x_uart.c.

As I see, it's due to this bad configuration.

With best regards;
