LL-Function for Clearing RXNE_RXFNE Flag in USART missing

[MootSeeker]

Describe the set-up STM32G031F8P6 IDE Version 1.10.1 / Package Version: 1.6.1

Describe the bug The function to clear RXNE flag in LL-Library is missing

How To Reproduce Function is missing

Additional context Please add this function. I think it should look like this:

__STATIC_INLINE void LL_USART_ClearFlag_RXNE_RXFNE(USART_TypeDef *USARTx) { CLEAR_BIT(USART2->ISR, USART_ISR_RXNE_RXFNE); }

Hi @MootSeeker,

The RXNE flag could be cleared simply by performing a read operation on the RDR register. You can thus simply use the code snippet below to clear the flag.

READ_REG(husart->Instance->RDR);
