Detailed Description

UART control functions.

  ==============================================================================
                      ##### Peripheral Control functions #####
  ==============================================================================  
  [..]
    This subsection provides a set of functions allowing to control the UART:
    (+) HAL_LIN_SendBreak() API can be helpful to transmit the break character.
    (+) HAL_MultiProcessor_EnterMuteMode() API can be helpful to enter the UART in mute mode. 
    (+) HAL_MultiProcessor_ExitMuteMode() API can be helpful to exit the UART mute mode by software.
