CubeMX 6.4 generate codes with a wrong statement about UART4 in STM32F303RC.

[yundm2]

When set TX Pin Active Level Inversion to Enable, CubeMX generate a wrong statment:

LL_USART_SetRXPinLevel(UART4, UART_ADVFEATURE_RXINV_ENABLE);

Not the OP but it's easy enough to replicate.

Seems like the LL library generation in CubeMX is still lacking. Lots of examples like this.

UART_ADVFEATURE_RXINV_ENABLE exists, but of course is in the HAL library, not the LL.
