DDL_USART_ConfigAsyncMode()

__STATIC_INLINE void DDL_USART_ConfigAsyncMode

(

USART_TypeDef *

USARTx

)

Perform basic configuration of USART for enabling use in Asynchronous Mode (UART).

Note

In UART mode, the following bits must be kept cleared:

• LINEN bit in the USART_CTRL2 register,
• CLKEN bit in the USART_CTRL2 register,
• SCEN bit in the USART_CTRL3 register,
• IREN bit in the USART_CTRL3 register,
• HDSEL bit in the USART_CTRL3 register.

Call of this function is equivalent to following function call sequence :

• Clear LINEN in CTRL2 using DDL_USART_DisableLIN() function
• Clear CLKEN in CTRL2 using DDL_USART_DisableSCLKOutput() function
• Clear SCEN in CTRL3 using DDL_USART_DisableSmartcard() function
• Clear IREN in CTRL3 using DDL_USART_DisableIrda() function
• Clear HDSEL in CTRL3 using DDL_USART_DisableHalfDuplex() function

Other remaining configurations items related to Asynchronous Mode (as Baud Rate, Word length, Parity, ...) should be set using dedicated functions
