UART advance feature config procedure is somewaht tedious and mistake prone

[flespark]

When I want config stm32wl usart tx logic level in reversion, I have to init UART such as:

  huart2.Instance = USART1;
  huart2.Init.BaudRate = 115200;
  huart2.Init.WordLength = UART_WORDLENGTH_8B;
  huart2.Init.StopBits = UART_STOPBITS_1;
  huart2.Init.Parity = UART_PARITY_NONE;
  huart2.Init.Mode = UART_MODE_TX_RX;
  huart2.Init.HwFlowCtl = UART_HWCONTROL_NONE;
  huart2.Init.OverSampling = UART_OVERSAMPLING_16;
  huart2.Init.OneBitSampling = UART_ONE_BIT_SAMPLE_DISABLE;
  huart2.Init.ClockPrescaler = UART_PRESCALER_DIV1;
// config UART advance feature
  huart2.AdvancedInit.AdvFeatureInit = UART_ADVFEATURE_DATAINVERT_INIT | UART_ADVFEATURE_TXINVERT_INIT;
  huart2.AdvancedInit.TxPinLevelInvert = USART_CR2_TXINV;
  huart2.AdvancedInit.DataInvert = USART_CR2_DATAINV;

  if (HAL_UART_Init(&huart2) != HAL_OK)
  {
    Error_Handler();
  }

The config code of advanced feature look tedious and mistake-prone without help of cubemx，maybe the define AdvancedInit as uint32_t instead of UART_AdvFeatureInitTypeDef, only assign value to huart2.AdvancedInit.AdvFeatureInit , then UART_AdvFeatureConfig do well the remaining work. that looks more resonable
