<p>Initialization and Configuration functions. </p>
<pre class="fragment"> ===============================================================================
##### 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),
the possible USART frame formats are as listed in the following table:
+-------------------------------------------------------------+
| M bit | PCE bit | USART frame |
|---------------------|---------------------------------------|
| 0 | 0 | | SB | 8 bit data | STB | |
|---------|-----------|---------------------------------------|
| 0 | 1 | | SB | 7 bit data | PB | STB | |
|---------|-----------|---------------------------------------|
| 1 | 0 | | SB | 9 bit data | STB | |
|---------|-----------|---------------------------------------|
| 1 | 1 | | SB | 8 bit data | PB | STB | |
+-------------------------------------------------------------+
(++) Hardware flow control
(++) Receiver/transmitter modes
[..]
The USART_Init() function follows the USART asynchronous configuration
procedure (details for the procedure are available in reference manual (RM0090)).
(+) For the synchronous mode in addition to the asynchronous mode parameters these
parameters should be also configured:
(++) USART Clock Enabled
(++) USART polarity
(++) USART phase
(++) USART LastBit
[..]
These parameters can be configured using the USART_ClockInit() function.</pre> <h2 class="groupheader">Function Documentation</h2>
