+ * @brief SMARTCARD HAL module driver.
+ * This file provides firmware functions to manage the following
+ * functionalities of the SMARTCARD peripheral:
+ * + Initialization and de-initialization functions
+ * + IO operation functions
+ * + Peripheral State and Errors functions
+ *
+ @verbatim
+ ==============================================================================
+ ##### How to use this driver #####
+ ==============================================================================
+ [..]
+ The SMARTCARD HAL driver can be used as follows:
+
+ (#) Declare a SMARTCARD_HandleTypeDef handle structure.
+ (#) Initialize the SMARTCARD low level resources by implementing the HAL_SMARTCARD_MspInit() API:
+ (##) Enable the USARTx interface clock.
+ (##) SMARTCARD pins configuration:
+ (+++) Enable the clock for the SMARTCARD GPIOs.
+ (+++) Configure these SMARTCARD 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.
+ (##) 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 stream.
+ (+++) Enable the DMAx interface clock.
+ (+++) Configure the declared DMA handle structure with the required Tx/Rx parameters.
+ (+++) Configure the DMA Tx/Rx Stream.
+ (+++) 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 Stream.
+
+ (#) Program the Baud Rate, Word Length , Stop Bit, Parity, Hardware
+ flow control and Mode(Receiver/Transmitter) in the SMARTCARD Init structure.
+
+ (#) Initialize the SMARTCARD registers by calling the HAL_SMARTCARD_Init() API:
+ (++) These APIs configure also the low level Hardware GPIO, CLOCK, CORTEX...etc)
+ by calling the customized HAL_SMARTCARD_MspInit() API.
+ [..]
+ (@) The specific SMARTCARD 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.
+
+ [..]
+ Three operation modes are available within this driver :
+
+ *** Polling mode IO operation ***
+ =================================
+ [..]
+ (+) Send an amount of data in blocking mode using HAL_SMARTCARD_Transmit()
+ (+) Receive an amount of data in blocking mode using HAL_SMARTCARD_Receive()
+
+ *** Interrupt mode IO operation ***
+ ===================================
+ [..]
+ (+) Send an amount of data in non blocking mode using HAL_SMARTCARD_Transmit_IT()
+ (+) At transmission end of transfer HAL_SMARTCARD_TxCpltCallback is executed and user can
+ add his own code by customization of function pointer HAL_SMARTCARD_TxCpltCallback
+ (+) Receive an amount of data in non blocking mode using HAL_SMARTCARD_Receive_IT()
+ (+) At reception end of transfer HAL_SMARTCARD_RxCpltCallback is executed and user can
+ add his own code by customization of function pointer HAL_SMARTCARD_RxCpltCallback
+ (+) In case of transfer Error, HAL_SMARTCARD_ErrorCallback() function is executed and user can
+ add his own code by customization of function pointer HAL_SMARTCARD_ErrorCallback
+
+ *** DMA mode IO operation ***
+ ==============================
+ [..]
+ (+) Send an amount of data in non blocking mode (DMA) using HAL_SMARTCARD_Transmit_DMA()
+ (+) At transmission end of transfer HAL_SMARTCARD_TxCpltCallback is executed and user can
+ add his own code by customization of function pointer HAL_SMARTCARD_TxCpltCallback
+ (+) Receive an amount of data in non blocking mode (DMA) using HAL_SMARTCARD_Receive_DMA()
+ (+) At reception end of transfer HAL_SMARTCARD_RxCpltCallback is executed and user can
+ add his own code by customization of function pointer HAL_SMARTCARD_RxCpltCallback
+ (+) In case of transfer Error, HAL_SMARTCARD_ErrorCallback() function is executed and user can
+ add his own code by customization of function pointer HAL_SMARTCARD_ErrorCallback
+
+ *** SMARTCARD HAL driver macros list ***
+ =============================================
+ [..]
+ Below the list of most used macros in SMARTCARD HAL driver.
+
+ (+) __HAL_SMARTCARD_ENABLE: Enable the SMARTCARD peripheral
+ (+) __HAL_SMARTCARD_DISABLE: Disable the SMARTCARD peripheral
+ (+) __HAL_SMARTCARD_GET_FLAG : Check whether the specified SMARTCARD flag is set or not
+ (+) __HAL_SMARTCARD_CLEAR_FLAG : Clear the specified SMARTCARD pending flag
+ (+) __HAL_SMARTCARD_ENABLE_IT: Enable the specified SMARTCARD interrupt
+ (+) __HAL_SMARTCARD_DISABLE_IT: Disable the specified SMARTCARD interrupt
+
+ [..]

+ ##### Initialization and Configuration functions #####
+ ==============================================================================
+ [..]
+ This subsection provides a set of functions allowing to initialize the USART
+ in Smartcard mode.
+ [..]
+ The Smartcard interface is designed to support asynchronous protocol Smartcards as
+ defined in the ISO 7816-3 standard.
+ [..]
+ The USART can provide a clock to the smartcard through the SCLK output.
+ In smartcard mode, SCLK is not associated to the communication but is simply derived
+ from the internal peripheral input clock through a 5-bit prescaler.
+ [..]
+ (+) For the Smartcard mode only these parameters can be configured:
+ (++) Baud Rate
+ (++) Word Length => Should be 9 bits (8 bits + parity)
+ (++) Stop Bit
+ (++) Parity: => Should be enabled
+ (++) USART polarity
+ (++) USART phase
+ (++) USART LastBit
+ (++) Receiver/transmitter modes
+ (++) Prescaler
+ (++) GuardTime
+ (++) NACKState: The Smartcard NACK state
+
+ (+) Recommended SmartCard interface configuration to get the Answer to Reset from the Card:
+ (++) Word Length = 9 Bits
+ (++) 1.5 Stop Bit
+ (++) Even parity
+ (++) BaudRate = 12096 baud
+ (++) Tx and Rx enabled
+ [..]
+ Please refer to the ISO 7816-3 specification for more details.
+
+ [..]
+ (@) It is also possible to choose 0.5 stop bit for receiving but it is recommended
+ to use 1.5 stop bits for both transmitting and receiving to avoid switching
+ between the two configurations.
+ [..]
+ The HAL_SMARTCARD_Init() function follows the USART SmartCard configuration
+ procedure (details for the procedure are available in reference manual (RM0329)).
+
+@endverbatim
+
+ The SMARTCARD frame format is given in the following table:
+ +-------------------------------------------------------------+
+ | M bit | PCE bit | SMARTCARD frame |
+ |---------------------|---------------------------------------|
+ | 1 | 1 | | SB | 8 bit data | PB | STB | |
