  This subsection provides a set of functions allowing to initialize the USARTx
  associated to the SmartCard.
  (+) These parameters can be configured:
      (++) Baud Rate
      (++) Parity: parity should be enabled, frame Length is fixed to 8 bits plus parity
      (++) Receiver/transmitter modes
      (++) Synchronous mode (and if enabled, phase, polarity and last bit parameters)
      (++) Prescaler value
      (++) Guard bit time
      (++) NACK enabling or disabling on transmission error

  (+) The following advanced features can be configured as well:
      (++) TX and/or RX pin level inversion
      (++) data logical level inversion
      (++) RX and TX pins swap
      (++) RX overrun detection disabling
      (++) DMA disabling on RX error
      (++) MSB first on communication line
      (++) Time out enabling (and if activated, timeout value)
      (++) Block length
      (++) Auto-retry counter

  The HAL_SMARTCARD_Init() API follows the USART synchronous configuration procedures
  (details for the procedures are available in reference manual).
