stm32f4 - USART가 데이터를 수신 할 수 없습니다

다음 코드의 문제점을 이해하지 못합니다. 모두 전송에 적합하지만 수신에 대해서는 인터럽트가 호출되지 않습니다.

오실로스코프는 정확한 송수신 데이터를 보여줍니다.

stm32f413Z 핵 보드입니다.

업데이트 : HAL과 동일하게 시도했지만 여기에서 USART6_IRQHandler 함수도 rx에 대해 호출되지 않았습니다.

인터럽트 루틴은 다음과 같습니다 :

void USART6_IRQHandler(void)
{
    uint32_t stateflg;
    if (LL_USART_IsActiveFlag_RXNE(USART6) || LL_USART_IsActiveFlag_ORE(USART6))
    {
        LL_USART_ReceiveData8(USART6);
    }
    if (LL_USART_IsActiveFlag_TXE(USART6))
    {
        uint8_t data = 0;
    }
}
