Initialization and Configuration functions.
==============================================================================
##### Initialization and Configuration functions #####
==============================================================================
[..]
This subsection provides a set of functions allowing to initialize the USART
in asynchronous and in synchronous modes.
(+) For the asynchronous mode only these parameters can be configured:
(++) Baud Rate
(++) Word Length
(++) Stop Bit
(++) Parity: If the parity is enabled, then the MSB bit of the data written
in the data register is transmitted but is changed by the parity bit.
Depending on the frame length defined by the M bit (8-bits or 9-bits),
please refer to Reference manual for possible USART frame formats.
(++) USART polarity
(++) USART phase
(++) USART LastBit
(++) Receiver/transmitter modes
[..]
The HAL_USART_Init() function follows the USART synchronous configuration
procedures (details for the procedures are available in reference manual
(RM0430 for STM32F4X3xx MCUs and RM0402 for STM32F412xx MCUs
RM0383 for STM32F411xC/E MCUs and RM0401 for STM32F410xx MCUs
RM0090 for STM32F4X5xx/STM32F4X7xx/STM32F429xx/STM32F439xx MCUs
RM0390 for STM32F446xx MCUs and RM0386 for STM32F469xx/STM32F479xx MCUs)).
