+ * @brief SMARTCARD HAL module driver.
+ *
+ * This file provides firmware functions to manage the following
+ * functionalities of the SmartCard.
+ * + Initialization and de-initialization functions
+ * + IO operation functions
+ * + Peripheral Control functions
+ *
+ *
+ @verbatim
+ ===============================================================================
+ ##### How to use this driver #####
+ ===============================================================================
+ [..]
+ The SMARTCARD HAL driver can be used as follows:
+
+ (#) Declare a SMARTCARD_HandleTypeDef handle structure.
+ (#) Associate a USART to the SMARTCARD handle hsmartcard.
+ (#) Initialize the SMARTCARD low level resources by implementing the HAL_SMARTCARD_MspInit ()API:
+ (##) Enable the USARTx interface clock.
+ (##) USART pins configuration:
+ (+) Enable the clock for the USART GPIOs.
+ (+) Configure these USART pins as alternate function pull-up.
+ (##) NVIC configuration if you need to use interrupt process (HAL_SMARTCARD_Transmit_IT()
+ and HAL_SMARTCARD_Receive_IT() APIs):
+ (+) Configure the USARTx interrupt priority.
+ (+) Enable the NVIC USART IRQ handle.
+ (@) The specific USART interrupts (Transmission complete interrupt,
+ RXNE interrupt and Error Interrupts) will be managed using the macros
+ __HAL_SMARTCARD_ENABLE_IT() and __HAL_SMARTCARD_DISABLE_IT() inside the transmit and receive process.
+ (##) DMA Configuration if you need to use DMA process (HAL_SMARTCARD_Transmit_DMA()
+ and HAL_SMARTCARD_Receive_DMA() APIs):
+ (+) Declare a DMA handle structure for the Tx/Rx channel.
+ (+) Enable the DMAx interface clock.
+ (+) Configure the declared DMA handle structure with the required Tx/Rx parameters.
+ (+) Configure the DMA Tx/Rx channel.
+ (+) Associate the initialized DMA handle to the SMARTCARD DMA Tx/Rx handle.
+ (+) Configure the priority and enable the NVIC for the transfer complete interrupt on the DMA Tx/Rx channel.
+
+ (#) Program the Baud Rate, Parity, Mode(Receiver/Transmitter), clock enabling/disabling and accordingly,
+ the clock parameters (parity, phase, last bit), prescaler value, guard time and NACK on transmission
+ error enabling or disabling in the hsmartcard Init structure.
+
+ (#) If required, program SMARTCARD advanced features (TX/RX pins swap, TimeOut, auto-retry counter,...)
+ in the hsmartcard AdvancedInit structure.
+
+ (#) Initialize the SMARTCARD associated USART registers by calling
+ the HAL_SMARTCARD_Init() API.
+
+ (@) HAL_SMARTCARD_Init() API also configure also the low level Hardware GPIO, CLOCK, CORTEX...etc) by
+ calling the customized HAL_SMARTCARD_MspInit() API.

+ 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:
+ the USART frame format is given in the following table:
+ +---------------------------------------------------------------+
+ | M bit | PCE bit | USART frame |
+ |---------------------|-----------------------------------------|
+ | 1 | 1 | | SB | 8 bit data | PB | STB | |
+ +---------------------------------------------------------------+

+ | M1M0 bits | PCE bit | USART frame |
+ |-----------------------|---------------------------------------|
+ | 01 | 1 | | SB | 8 bit data | PB | STB | |
+ +---------------------------------------------------------------+
+
+ (++) 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 follow respectively the USART (a)synchronous configuration procedures
+ (details for the procedures are available in reference manual).
