Function Name
void USART_ITConfig ( USART_TypeDef * USARTx, uint32_t
USART_IT, FunctionalState NewState)
Function Description
Enables or disables the specified USART interrupts.
Parameters
 USARTx : Select the USART peripheral. This parameter can
be one of the following values: USART1 or USART2 or
USART3 or UART4 or UART5.

 USART_IT_LBD : LIN Break detection interrupt.
 USART_IT_TXE : Tansmit Data Register empty
interrupt.
 USART_IT_TC : Transmission complete interrupt.
 USART_IT_RXNE : Receive Data register not empty
interrupt.
 USART_IT_IDLE : Idle line detection interrupt.
 USART_IT_PE : Parity Error interrupt.
 USART_IT_ERR : Error interrupt(Frame error, noise
error, overrun error)
 NewState : new state of the specified USARTx interrupts.
This parameter can be: ENABLE or DISABLE.
Return values
 None.
Notes
 None.
