__HANDLE__: specifies the USART
Handle. This parameter can be
USARTx where x: 1, 2, 3, 4, 5, 6, 7 or
8 to select the USART or UART
peripheral.
__FLAG__: specifies the flag to
check. This parameter can be one of
the following values:
IRDA_FLAG_TXE: Transmit data
register empty flag
IRDA_FLAG_TC: Transmission
Complete flag
IRDA_FLAG_RXNE: Receive
data register not empty flag
IRDA_FLAG_IDLE: Idle Line
detection flag
IRDA_FLAG_ORE: OverRun
Error flag
IRDA_FLAG_NE: Noise Error
flag
IRDA_FLAG_FE: Framing Error
flag
IRDA_FLAG_PE: Parity Error
flag
Return value:
The: new state of __FLAG__ (TRUE
or FALSE).
__HAL_IRDA_CLEAR_FLAG
Description:
Clears the specified IRDA pending
