This subsection provides a set of functions allowing to return the State of SmartCard

- (+) HAL_SMARTCARD_GetState() API can be helpful to check in run-time the state of the SMARTCARD peripheral
- (+) HAL_SMARTCARD_GetError() check in run-time errors that could be occurred during
- communication.
-
- (+) SMARTCARD_SetConfig() API configures the SMARTCARD peripheral
- (+) SMARTCARD_AdvFeatureConfig() API optionally configures the SMARTCARD advanced features
- (+) SMARTCARD_CheckIdleState() API ensures that TEACK and/or REACK are set after initialization
+ handle and also return Peripheral Errors occurred during communication process
+ (+) HAL_SMARTCARD_GetState() API can be helpful to check in run-time the state
+ of the SMARTCARD peripheral.
+ (+) HAL_SMARTCARD_GetError() checks in run-time errors that could occur during
