STM32Cube_FW_G0_V1.6.1 drivers

We are using a new STM32G0B which requires we a shift to the new STM LL drivers and have come across a discrepancy with the USART ICR register drivers. RM0454 Pg 851 references bit 5 of the USART ICR register as RXFNE: RXFIFO not empty. The Low Level drivers v1.6.1 say that this bit is the TX FIFO empty flag. The drivers also declare a inline LL_USART_ClearFlag_TXFE() which uses this bit definition. Is the Reference manual correct or drivers? I'm guessing reference manual.

Thanks.
