Notes

In Half Duplex mode, the following bits must be kept cleared: - LINEN bit in the USART_CR2 register, - CLKEN bit in the USART_CR2 register, - SCEN bit in the USART_CR3 register, - IREN bit in the USART_CR3 register, This function also sets the UART/USART in Half Duplex mode. Macro IS_UART_HALFDUPLEX_INSTANCE(USARTx) can be used to check whether or not Half-Duplex mode is supported by the USARTx instance. Call of this function is equivalent to following function call sequence : - Clear LINEN in CR2 using LL_USART_DisableLIN() function - Clear CLKEN in CR2 using LL_USART_DisableSCLKOutput() function - Clear SCEN in CR3 using LL_USART_DisableSmartcard() function - Clear IREN in CR3 using LL_USART_DisableIrda() function - Set HDSEL in CR3 using LL_USART_EnableHalfDuplex() function Other remaining configurations items related to Half Duplex Mode (as Baud Rate, Word length, Parity, ...) should be set using dedicated functions CR2 CLKEN LL_USART_ConfigHalfDuplexMode\n CR3 HDSEL LL_USART_ConfigHalfDuplexMode\n CR3 SCEN LL_USART_ConfigHalfDuplexMode\n CR3 IREN LL_USART_ConfigHalfDuplexMode
