  (#) FIFO mode enabling/disabling and RX/TX FIFO threshold programming.

      -@- When USART operates in FIFO mode, FIFO mode must be enabled prior
          starting RX/TX transfers. Also RX/TX FIFO thresholds must be
          configured prior starting RX/TX transfers.

  (#) Slave mode enabling/disabling and NSS pin configuration.

      -@- When USART operates in Slave mode, Slave mode must be enabled prior
          starting RX/TX transfers.
