sahilmgandhi	18:6a4db94011d3	21	(#) Declare a SMARTCARD_HandleTypeDef handle structure.
sahilmgandhi	18:6a4db94011d3	22	(#) Initialize the SMARTCARD low level resources by implementing the HAL_SMARTCARD_MspInit() API:

sahilmgandhi	18:6a4db94011d3	377	[..]
sahilmgandhi	18:6a4db94011d3	378	Smartcard is a single wire half duplex communication protocol.
sahilmgandhi	18:6a4db94011d3	379	The Smartcard interface is designed to support asynchronous protocol Smartcards as
sahilmgandhi	18:6a4db94011d3	380	defined in the ISO 7816-3 standard. The USART should be configured as:
sahilmgandhi	18:6a4db94011d3	381	(+) 8 bits plus parity: where M=1 and PCE=1 in the USART_CR1 register
sahilmgandhi	18:6a4db94011d3	382	(+) 1.5 stop bits when transmitting and receiving: where STOP=11 in the USART_CR2 register.

sahilmgandhi	18:6a4db94011d3	386	The HAL status of all data processing is returned by the same function
sahilmgandhi	18:6a4db94011d3	387	after finishing transfer.

sahilmgandhi	18:6a4db94011d3	389	or DMA, These APIs return the HAL status.
