+ ##### Initialization and Configuration functions #####
+ ==============================================================================
+ [..]
+ This subsection provides a set of functions allowing to initialize the USARTx or the UARTy
+ in asynchronous mode.
+ (+) For the asynchronous mode only these parameters can be configured:
+ (++) Baud Rate
+ (++) Word Length (Fixed to 8-bits only for LIN mode)
+ (++) 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),
+ the possible UART frame formats are as listed in the following table:
+ |-----------|-----------|---------------------------------------|
+ | M1M0 bits | PCE bit | UART frame |
+ |-----------------------|---------------------------------------|
+ | 00 | 0 | | SB | 8-bit data | STB | |
+ |-----------|-----------|---------------------------------------|
+ | 00 | 1 | | SB | 7-bit data | PB | STB | |
+ |-----------|-----------|---------------------------------------|
+ | 01 | 0 | | SB | 9-bit data | STB | |
+ |-----------|-----------|---------------------------------------|
+ | 01 | 1 | | SB | 8-bit data | PB | STB | |
+ +---------------------------------------------------------------+
+ | 10 | 0 | | SB | 7-bit data | STB | |
+ |-----------|-----------|---------------------------------------|
+ | 10 | 1 | | SB | 6-bit data | PB | STB | |
+ +---------------------------------------------------------------+
+ (++) Hardware flow control
+ (++) Receiver/transmitter modes
+ (++) Over Sampling Method
+ (++) One-Bit Sampling Method
+ (+) For the asynchronous mode, the following advanced features can be configured as well:
+ (++) TX and/or RX pin level inversion
+ (++) data logical level inversion
+ (++) RX and TX pins swap
+ (++) RX overrun detection disabling
+ (++) DMA disabling on RX error
+ (++) MSB first on communication line
+ (++) auto Baud rate detection
+ [..]
+ The HAL_LIN_Init() and HAL_RS485Ex_Init() APIs follows respectively the LIN and
+ the UART RS485 mode configuration procedures (details for the procedures are
+ available in reference manual).
