void USART_SWAPPinCmd ( USART_TypeDef USARTx,
FunctionalState  NewState 
)

Enables or disables the swap Tx/Rx pins.

Parameters
USARTxSelect the USART peripheral. This parameter can be one of the following values: USART1 or USART2 or USART3 or UART4 or UART5.
NewStatenew state of the USARTx TX/RX pins pinout. This parameter can be: ENABLE or DISABLE.
  • ENABLE: The TX and RX pins functions are swapped.
  • DISABLE: TX/RX pins are used as defined in standard pinout
Note
This function has to be called before calling USART_Cmd() function.
