Detailed Description

UART State and Errors functions.

  ==============================================================================
                 ##### Peripheral State and Errors functions #####
  ==============================================================================  
 [..]
   This subsection provides a set of functions allowing to return the State of 
   UART communication process, return Peripheral Errors occurred during communication 
   process
   (+) HAL_UART_GetState() API can be helpful to check in run-time the state of the UART peripheral.
   (+) HAL_UART_GetError() check in run-time errors that could be occurred during communication.
