◆ __HAL_USART_CLEAR_FEFLAG

#define __HAL_USART_CLEAR_FEFLAG ( __HANDLE__ ) __HAL_USART_CLEAR_PEFLAG(__HANDLE__)

Clear the USART FE pending flag.

Parameters

HANDLE specifies the USART Handle. This parameter can be USARTx where x: 1, 2, 3 or 6 to select the USART peripheral.

Return values

None

◆ __HAL_USART_CLEAR_FLAG

#define __HAL_USART_CLEAR_FLAG	(	__HANDLE__,
		__FLAG__
	)	((__HANDLE__)->Instance->SR = ~(__FLAG__))

Clears the specified Smartcard pending flags.

Parameters

<strong>HANDLE</strong>	specifies the USART Handle. This parameter can be USARTx where x: 1, 2, 3 or 6 to select the USART peripheral.
<strong>FLAG</strong>	specifies the flag to check. This parameter can be any combination of the following values: USART_FLAG_TC: Transmission Complete flag. USART_FLAG_RXNE: Receive data register not empty flag.

Note: PE (Parity error), FE (Framing error), NE (Noise error), ORE (Overrun error) and IDLE (Idle line detected) flags are cleared by software sequence: a read operation to USART_SR register followed by a read operation to USART_DR register.; RXNE flag can be also cleared by a read to the USART_DR register.; TC flag can be also cleared by software sequence: a read operation to USART_SR register followed by a write operation to USART_DR register.; TXE flag is cleared only by a write to the USART_DR register.
