23.2.17.6 USART_GetITStatus
Function Name
ITStatus USART_GetITStatus ( USART_TypeDef * USARTx,
uint32_t USART_IT)
Function Description
Checks whether the specified USART interrupt has occurred or
not.
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 : specifies the USART interrupt source to check.
This parameter can be one of the following values:
 USART_IT_WU : Wake up interrupt.
 USART_IT_CM : Character match interrupt.
 USART_IT_EOB : End of block interrupt.
 USART_IT_RTO : Receive time out interrupt.
 USART_IT_CTS : CTS change interrupt.
 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_ORE : OverRun Error interrupt.
 USART_IT_NE : Noise Error interrupt.
 USART_IT_FE : Framing Error interrupt.
 USART_IT_PE : Parity Error interrupt.
Return values
 The new state of USART_IT (SET or RESET).
Notes
 None.
