/** @brief  Disable RTS flow control
661
  *         This macro allows to disable RTS hardware flow control for a given UART instance,
662
  *         without need to call HAL_UART_Init() function.
663
  *         As involving direct access to UART registers, usage of this macro should be fully endorsed by user.
664
  * @note   As macro is expected to be used for modifying RTS Hw flow control feature activation, without need
665
  *         for USART instance Deinit/Init, following conditions for macro call should be fulfilled :
666
  *           - UART instance should have already been initialised (through call of HAL_UART_Init() )
667
  *           - macro could only be called when corresponding UART instance is disabled (i.e __HAL_UART_DISABLE(__HANDLE__))
668
  *             and should be followed by an Enable macro (i.e __HAL_UART_ENABLE(__HANDLE__)).
669
  * @param  __HANDLE__ specifies the UART Handle.
670
  *         The Handle Instance can be any USARTx (supporting the HW Flow control feature).
671
  *         It is used to select the USART peripheral (USART availability and x value depending on device).
672
  * @retval None
