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.
Clear the IRDA PE pending flag.

Handle. This parameter can be
USARTx where x: 1, 2, 3, 4, 5, 6, 7 or
8 to select the USART or UART
peripheral.

__HANDLE__: specifies the USART
Handle. This parameter can be
