None
Checks whether the specified UART
interrupt has occurred or not.
__HANDLE__: specifies the UART
Handle. This parameter can be
UARTx where x: 1, 2, 3, 4, 5, 6, 7 or
8 to select the USART or UART
peripheral.
__IT__: specifies the UART interrupt
source to check. This parameter can
be one of the following values:
UART_IT_CTS: CTS change
interrupt (not available for
UART4 and UART5)
UART_IT_LBD: LIN Break
detection interrupt
UART_IT_TXE: Transmit Data
Register empty interrupt
UART_IT_TC: Transmission
complete interrupt
UART_IT_RXNE: Receive Data
register not empty interrupt
UART_IT_IDLE: Idle line
detection interrupt
USART_IT_ERR: Error interrupt
The: new state of __IT__ (TRUE or
FALSE).
